2 years ago I have investigated the stack traces.
Two stack traces (2022-04-25_10-50-14.0976_+0200-10370900cb31f02fbe46c189a186c85709ec1532.txt and 2022-04-25_10-50-14.0976_+0200-10370900cb31f02fbe46c189a186c85709ec1532.txt) is similar to https://github.com/realm/realm-core/issues/5344 - the realm::Array::init_from_ref() call is in both.
Moreover, the stack traces 2022-04-24_11-06-35.7773_+0800-1dc9a5cb656aa8f4597272dea4f4e2fd2fe4b7d3.txt and 2022-04-24_09-49-16.5911_+0800-5d54e08447eada3d190a81ad0583993fbed9e685.txt have some similarity (memmove() in particular).

2 years ago Thanks @kneth for investigating. I have a hard time evaluating the resemblance of the stack traces, but I see from the error report bread crumbs in our most frequent crash that - like https://github.com/realm/realm-core/issues/5344 - it also happens on app launch (where we create a Realm instance).
I get a little nervous if our stability issues share root cause with https://github.com/realm/realm-core/issues/5344 as it has been open for more than a month without being updated - is it still being investigated?
@fronck We still didn't find a way to reproduce the issue, but we got symbolication of the native iOS stack trace working in the Bugsnag error reports and this is an example of the stack trace of the crash which we see most (and very) frequently:

2 years ago Hi again @kneth @fronck.
Unfortunately we still haven't been able to reproduce the crashes. But let me add some information from looking at the breadcrumbs of the SIGABRT crash reports: The app seems to always be in the background when it occurs - and it's either triggered when reading/writing or when instantiating the realm object during app launch (we perform this app launch initialization in the background when our app is woken up by an iBeacon or location event).
To me, the stack traces look a bit different for the SIGABRT crash - in hope of that being true and helpful, here are a few more example stack traces:

2 years ago Hi @martinpoulsen, thanks for all the details. We are doing some investigation into this issue right now.
Are you able to share more information about what your app is doing when it receives a location event? If you have some sample code for how you are handling this, that would be interesting.
Our prime suspect is that the app's data could be being encrypted by iOS when it goes into the background, then when it tries to interact with the Realm in the background, the (still open) Realm is reading OS-encrypted data rather than what it expects, and so crashes in seemingly random places – because it is receiving garbage data, essentially. The Realm Swift docs talk about this encryption issue.
However, I created a simple test app which is woken from the background via a silent push notification (this seemed like it would be easier to test than location) and writes and reads from the Realm when it is awoken, and I haven't seen any issues so far. If you can share a bit more about what your app is doing when awoken, then we can try to simulate a more realistic workload. I can also try using location instead of push notification, in case this has any bearing on how iOS behaves – if you have tips on how best to test location events, that would save me some research!
martinpoulsen
commented
2 years ago Hi @tomduncalf, happy to hear you are investigating this issue 🙏
Essentially, what our app does is tracking trips for our users for mileage reimbursement purposes. When resumed or woken up by a location (or an iBeacon or a geofence) it decides whether it should be record as part of a trip. If that's the case (i.e. the user is currently tracking a trip), it will be stored on a Trip realm model which has a route property (i.e. a list of locations). However, if the app is not initialized when receiving the location, it will first instantiate a Realm instance for the user - we do this only in the app launch flow.
One thing that seems important when talking about reproducing the crashes is that they are not evenly distributed across our users. It is "only" affecting ~ 2% of our iOS users (and no Android users) but those 2% experience enough crashes that our session stability is down from ~ 99% to ~ 90% across all iOS users. So unfortunately that might mean that it's hard to reproduce the crashes in a basic sample app. Btw, the users we have been in contact with and who have been hit by these crashes were able to get rid of them by deleting => reinstalling the app.
About the iOS file encryption, I'm wondering how that suddenly could start causing this magnitude of crashes after upgrading Realm from v. 10.10.1 => 10.13.0 (and still seeing them in v. 10.16.0) while seeing them very rarely before the upgrade.
I will continue to try and reproduce the crashes and also keep looking for patterns giving some clue about the cause.
tomduncalf
commented
2 years ago Thanks for the additional details @martinpoulsen, indeed that does make the iOS encryption thing seem a little less likely, though there could be some weird interaction of things. We're looking into what changed in Realm core between those versions but are yet to find anything suspicious.
Are you using encrypted Realms?
tomduncalf
commented
2 years ago One other question, when you say "seeing them very rarely before the upgrade" – were you seeing these crashes in some smaller volume before the upgrade, or not at all?
martinpoulsen
commented
2 years ago Hi @tomduncalf thanks again for looking into this!
We are not using encrypted realms.
And sorry for being vague about whether we have seen the errors before. It's only recently that we got the native side of iOS crash report stack traces symbolicated in our error reporting setup using Bugsnag (we did this when we recently saw a massive increase in iOS native crashes). We do have some SIGABRT crash reports from older app versions, but we don't know if they come from Realm. At least they are very infrequent.
I have now setup symbolication for the most recent build before the Realm upgrade so for future crashes from that app version, we will know - and I will make sure to update you on that.
tomduncalf

2 years ago Got it, no worries @martinpoulsen and thanks for confirming re: encryption. We're continuing to investigate as a priority, so I will keep you udpated and let you know if we have any other questions.
tomduncalf
commented
2 years ago @martinpoulsen Are you able to confirm if the realm::KeyNotFound errors all have different error messages, or are there clusters of similar messages? If you could supply a screenshot/copy of a sampling of them that would be interesting.
It looks like the realm::NoSuchTable errors don't have any specific data in the error message, just a generic error, but if you could validate that too it would be great!
tomduncalf
commented
2 years ago Also, if it's easy for you to supply some more stack traces (for any of the errors), that would be great so I can see if I can spot any patterns – if it's not convenient to do so via Github then you can email to realm-help@mongodb.com
tomduncalf
commented
2 years ago One other question @martinpoulsen, are you using Realm Sync?
tomduncalf
commented
2 years ago Sorry for the bombardment of messages @martinpoulsen, I'm asking questions as I think of them so I hope you don't mind! Are the users who hit this issue then unable to open your app at all? Or is it an intermittent issue (i.e. they get some crashes but can sometimes open the app fine)?
And do you see any crash logs for starting with Unable to open realm or Unable to open a realm? (This would indicate that the Realm is corrupted when we tried to open it)
martinpoulsen
commented
2 years ago @tomduncalf, I'm more than happy to assist in any way I can to get these issues resolved, please keep asking anything that could be useful!
The KeyNotFound and NoSuchTable seem to me to have pretty consistent stack traces. However, the KeyNotFound has been observed with at least two different realm models (RoutePoint and LogItem). I can confirm that the NoSuchTable error does not contain any specific error message in any of the stack traces that I've seen.
The SIGABRT crash looks more varying in its stack trace and so does a EXC_BAD_ACCESS crash which is about as frequent as KeyNotFound/NoSuchTable.
I have attached a sample of 10 stack traces for each of the crashes in the bottom. If it's helpful with a larger sample, just let me know. We would also be happy to give you access to our Bugsnag error reporting tool - again, just let me know.
We are not using Realm Sync, only a local database.
One thing I thought of mentioning is that we have two realm database instances running at all times - one for some global state (e.g. to keep track of currently logged in user) and one for user data (trips, etc).
I see very few errors with the Unable to open (a) realm message - around 1 per day (while the SIGABRT crash occurred almost 10.000 times the last 24 hours).
The few users we have been contacted by have experienced frequent crashes but not consistently in a way where they can never open the app. The breadcrumbs of the error reports supports this - the crashes are sometimes early in a session but usually not immediately when we create the realm instance. In many cases it happens when accessing realm to read/write at (for now) seemingly random times.

2 years ago Thanks for all the details and crash reports @martinpoulsen, that's really useful. I think this is plenty to go on, but if we determine that having access to your bug reporting tool would be useful we will let you know, thanks for the offer!
In the interim, I would suggest you advise users who have the issue to reinstall the app – is all your data being synced to your server by some other means so users should not lose data?
Do you know if you've had any incidences of users who have had to uninstall and reinstall hitting this same problem for a second time? Especially users who reinstalled a version of your app which uses Realm v10.16.0.
tomduncalf
commented
2 years ago A related question, are you aware of any new users who started with the latest version of your app (i.e. the one using Realm v10.16.0, rather than upgrading from an older version) hitting this issue? I'm wondering if the issue could be related to an older version of Realm and is now fixed (if the file is created with v10.16.0), or if it is still occurring with v10.16.0
martinpoulsen
commented
2 years ago Thanks @tomduncalf, advicing to reinstall the app is what our support team is currently doing when we get contacted by users who face these crashes - I'm not aware of a case where a user kept seeing the crashes after a reinstall, but we have only been in contact with a relatively small amount of users so far. If I see such a case at some point, I will let you know.
User data is synced to our servers via a custom sync API so luckily a reinstall will not cause loss of data.
Regarding new users (who started with v.10.16.0) facing the crash, this is one of the patterns I'm currently looking into, I will get back to you on that.

martinpoulsen
commented
2 years ago Hi again @tomduncalf I have looked at a sample of 200 SIGABRT crashes and made some observations:
It appears that there is a pattern of users being less likely to get the crash if they created their Realm db with 10.13.0 and much less likely if they created it with 10.16.0. Our app realm version release timeline looks like this:
Looking at the signup time of the users behind the 200 crash reports, it seems there are fewer than expected who signed up between April 1. and April 21. (where Realm was created with 10.13.0) - and much fewer than expected (none in the sample) created after April 21. (where Realm was created with 10.16.0). I'm comparing against a significant amount of users who signed up in March, February, January, etc:
I will increase the sample size and see if the pattern still holds.
tomduncalf
commented
2 years ago Thanks for your investigation @martinpoulsen, that is indeed very interesting. I'll focus my testing in on what happens when a Realm gets upgraded from 10.10.1 to 10.16.0 and let you know if I find anything

2 years ago @tomduncalf I now looked at ~450 users who got the SIGABRT crash. The pattern seems to still hold up pretty well. Only a single user in this sample signed up using (and only ever used) the most recent app version (which includes Realm 10.16.0) - this user has experienced both the SIGABRT crash and the EXC_BAD_ACCESS crash.
This is the user creation date of the of the sample:

commented
2 years ago Thanks @martinpoulsen!
I'm wondering if the "app was in background when it happened" element is a useful clue, or irrelevant... does your app frequently write to Realm when it's in the foreground too, or would the normal use case be with it in the background?
martinpoulsen
commented
2 years ago @tomduncalf it's not rare that the app writes to Realm while in foreground - e.g. when updating recorded trips (every trip is usually edited one or more times) or when the user creates trips by means of just inputting start/stop location rather than tracking GPS data. But most frequently we write GPS data to realm while the app is in the background, so I'm not sure if it's just a coincidence that the reports I have seen mostly happens in background.
I will follow up and investigate this more closely.
martinpoulsen
commented
1 year ago Hi @tomduncalf,
I have indexed the crash reports on whether the app is in foreground/background and they happen during app launch.
SIGABRT crash foreground/background distribution:
SIGABRT crash distribution on whether the app is launching:
The other crashes look similar in distribution though the relative amount of crashes in foreground is a little bit higher for realm::NoSuchTable / realm::KeyNotFound (around 1.5%).
In case it's interesting, here are a few stack traces from the SIGABRT crash while the app is in the foreground:
SIGABRT_foreground_1.txt SIGABRT_foreground_2.txt SIGABRT_foreground_3.txt

commented
1 year ago Thanks @martinpoulsen – seems like a pretty strong correlation there! I wonder if there's anything else that the cohort of users who are experiencing this issue have in common – for example are they all in the same country? Might sound weird but I've dealt with some really strange issues in my time and country was part of the cause of one so I never rule anything out, haha
martinpoulsen
commented
1 year ago Hi @tomduncalf.
I have also been wondering about what those users who experience the crashes could have in common but haven't found anything yet. The distribution of countries match our relative presence in those markets:
Btw, I am now looking at all ~850 users who experienced the SIGABRT crash. The pattern that these users primarily started using Realm 10.10.1 or earlier still holds. Here is the nr of affected users by signup week (notice that not a single user who signed up in May is affected):

1 year ago @tomduncalf just wanted to let you know that we have observed several instances of these crashes for users who only used the app with realm v. 10.16.0. There certainly seems to be a correlation between getting these crashes and going through a realm version migration, but it doesn't seem to be a necessary condition.

1 year ago Thanks for the update @martinpoulsen and I'm sorry to hear you are still having issues. I'm going to discuss this with the team again in light of that information, I'm afraid we didn't make any progress on tracking down the root cause so far.

1 year ago Do we know how prevalent this issue is? The majority of our users are long term users and started with an older version of realm, I am scared to upgrade on iOS. @martinpoulsen could you confirm that the crashes only happen when app is in the background?

1 year ago @Pingou we've not had any other reports of this exact issue.
We are aware of a few reports which seem related to memory leaks or crashes related to accessing freed memory, the ones we are tracking are:
The difficulty with all of these has been that they are relatively very rare, and we have been unable to reproduce them – we've tried various approaches to stress testing Realm JS and have not been successful. Also note that some of these are quite old and could have been fixed, but we are unable to prove that.
Our upcoming Hermes release changes quite a few things related to object ownership etc. in our C++ layer, so we hope should solve many such issues.
In the case of Martin's issue, we are not sure exactly what the cause is and again have not been able to reproduce it despite stress testing opening a Realm JS app in the background repeatedly, upgrading Realm between various versions etc.
This is something we are still investigating, obviously any crashes are a concern for us, but what I would say is that the volume of reports of such crashes is very low compared to the number of users we have. This issue is the first one that I am aware of where there has been any hypothetical link to Realm upgrades causing issues, and we've so far not been able to prove that.

1 year ago @Pingou 99.5% of these issues happen in the background in our case (see my update in this issue from May 23). But our app will continuously try to launch itself if terminated so that might be the reason why so many of the crashes happen while in background.

1 year ago @martinpoulsen Could you elaborate a little on what you mean by

please?

1 year ago @tomduncalf sure, our app is (under certain configurations) aiming to be active at all times to monitor the activity of the user (specifically to detect whether the user is driving). This includes launching itself from process death. So what happens for some of our users with these realm issues is that the app get's stuck in a loop where it crashes during app startup every time it tries to launch itself.

1 year ago Ah OK, how do you go about reopening the app when it has been terminated?

1 year ago We are listening for various events such as location updates, phone movements, power source change and iBeacon region state changes which will launch the app if terminated before the event gets delivered.

1 year ago @martinpoulsen Related to iBeacon, the trick mentioned in https://github.com/realm/realm-core/issues/5731#issuecomment-1224285742 might help you. We are considering adding a configuration option to do it so you don't have to deal with Objective C or Swift code.
Since we upgraded Realm from 10.10.1 => 10.13.0, we have experienced a big drop in stability on iOS and have been hit by what appears to be native memory management issues. Our crash reporting tool (Bugsnag) reports that the iOS app session stability dropped from ~ 99% to ~ 90%. We didn't update any other dependencies (or made any native code changes) in the release where we updated Realm and started seeing these issues. This is what the top crashes looked like with Realm 10.13.0:
Then we tried upgrading Realm from 10.13.0 => 10.16.0 (again without making changes to other app dependencies or making native code changes) but unfortunately the session stability did not improve. This is what the top crashes look like with Realm after the Realm upgrade to 10.16.0 (sorry about the non-symbolicated traces):
Both app versions with Realm 10.13.0 and 10.16.0 show realm::NoSuchTable and realm::KeyNotFound crashes. However, the most frequently reported crash comes in the form of a more general SIGABRT error report which it's my understanding could be rooted in any native module. Here's an example stack trace from the reported SIGABRT crash:
Here are a few crash reports retrieved through XCode which mention Realm in the stack trace - they are all from the app version which uses realm v. 10.16.0: 2022-04-2311-24-19.2673-0500-2fd0a5349d21e8624bedea7cadd05249a7ef257e.txt 2022-04-2409-49-16.5911+0800-5d54e08447eada3d190a81ad0583993fbed9e685.txt 2022-04-2411-06-35.7773+0800-1dc9a5cb656aa8f4597272dea4f4e2fd2fe4b7d3.txt 2022-04-2411-51-44.3257-0500-e80fd319087391b20fa73e248a7f66e80b34afa0.txt 2022-04-2413-26-48.1968+0200-00cc3ee3534c38956fa8190f226d1dd5d1a04af5.txt 2022-04-2510-50-14.0976+0200-10370900cb31f02fbe46c189a186c85709ec1532.txt
We realise that this issue is somewhat vague but unfortunately we haven't yet found a way to reproduce the crashes. Our hope is that some of the attached crash reports will be meaningful for the Realm team and either point to a Realm problem - or to something which we could be doing wrong but which only causes problems in these new realm versions.
We use Realm with react-native v. 0.65.2 (without Hermes)
