mega-cmd-server crashes

[srulikuk]

Just installed on a new server, there are a few 100k of files to sync however it keeps on crashing at random times with nothing useful in the debug log

I ran it 10 times with debug to file, the smallest the file was when it crashed was 150MB, the largest 3.8GB,

The last line in all the logs were "Transfer (DOWNLOAD) finished. File: ...." how can I get to the bottom of this?

Hi @srulikuk , a stack trace would help us find where the crash is happening. Here are some instructions (asuming debian based distro):

1 - install debug symbols sudo apt update && sudo apt install megacmd-dbg

2 - run mega-cmd-server in a debugger (you might need to install gdb) gdb mega-cmd-server It should say something like:

done.
(gdb) 

3 - Then run the program (type 'r' + Enter) Let it run until it crashes.

4 - once so, then type in the gdb console: 'thread apply all bt' Press "Enter" until the output is complete, and

5 - then please, scroll back and send us the entire output of that command.

I too am running into this. I am including my output as well. If this needs to be split into another issue, please let me know.

[polmr]

Thanks guys! Note: @srulikuk output didn't have the entire output (with the offending thread trace) and @bashfulrobot's didn't have which thread segfaulted (anyway it's thread 4 too ;-) ). Here comes the interesting part:

#0  mega::LocalNode::getlocalpath (this=0xffffffffffffffff, path=..., sdisable=sdisable@entry=true, localseparator=localseparator@entry=0x0) at src/node.cpp:1620
#1  0x00005555557a9e41 in mega::MegaNodePrivate::MegaNodePrivate (this=0x7fffbba87460, node=0x7fffbba6fa80) at src/megaapi_impl.cpp:463

this=0xffffffffffffffff -> this special value should never be accessed. This is very likely solved in newer SDK versions than the one used in current MEGAcmd version. We will soon release a new version that will probably fix that. Please, stay tuned and apologies for the inconveniences.

[srulikuk]

@polmr sorry about that, here is my full output, i also have this=0xffffffffffffffff in my output. in how long do you expect to have a fix and do you have a work around? (I am on ubuntu 20.04.2 LTS)

[srulikuk]

@polmr do you have an ETA?

[bashfulrobot]

Hi there, I'm just following up on this. I was considering a subscription, but this tool is critical for me and my use cases.

Thank you very much for your time.

[srulikuk]

@polmr any update?

[aabellagm]

Hi! We don't have a release date yet (it will be soon), but we can share with you the 1.5.0 RC1 packages which may fix your problems: https://mega.nz/folder/YsgSlCZL#iQYQo4Fkw5DimKxP9KIwDA

Install it on top of the one you currently have if any:

sudo apt install /path/to/downloaded/megacmd_1.5.0-1.1_amd64.deb

If you experience any crash, follow the instructions Pablo gave you above, but installing the megacmd-dbg_1.5.0-1.1_amd64.deb package in this link. Again, you can install it on top of the one you have.

If you install them, once the official 1.5.0 package is ready in our repositories, the package will be updated as any other package in your distro. No major problems are expected with this packages, but if you find any, please report! =)

I am just starting my sync tests back up, but so far, nothing seems to be failing thus far. :+1:

[srulikuk]

@aabellagm I tried to install megasync-xUbuntu_18.04_amd64.deb however i get dependency issues

The following packages have unmet dependencies:
 megasync : Depends: libraw16 (>= 0.16.0) but it is not installable

I installed libraw19 but it did not resolve the issue.

[aabellagm]

Hi @srulikuk I think you are using Ubuntu 20.04 and you are trying to install the package for Ubuntu 18.04.

In the link above, select xUbuntu_20.04 folder, then amd64 and download and install the package called megacmd_1.5.0-1.1_amd64.deb.

[srulikuk]

@aabellagm ooops, my bad. thanks

[srulikuk]

@aabellagm its been running without issue for the past 22 hours... will monitor but the main issue of crashing is now resolved. thanks

[srulikuk]

@bashfulrobot @polmr Since the 4th of October I am having a new issue, it only uploads empty dirs and not the content, restarting mega seems to upload all for a few hours, I tried to download the debug version form the link above but the files are no longer available.

[polmr]

Hi @srulikuk . MEGAcmd 1.5.0 is still pending release. The above link is down. These are our release candidate versions that are likely to have the fix for the issue mentioned above: https://mega.nz/folder/eBs0BIzC#4TRItAmn4yiIjYaRQczLZQ

Apologies for the inconvenience.

[srulikuk]

@polmr I have been running the dbg for past 18 hours, no crashes but I still have an issue with 1 sync where it only uploads empty dirs and not the contents, when I add a file manually to that dir it does upload but the files which come in via rsync every few hours do not upload until i stop and start mega again.

Not sure how to troubleshoot this.

[srulikuk]

@polmr ^ ?

[polmr]

Hi @srulikuk , apologies for the late response. It seems as if MEGAcmd was not receiving file system notifications for those files. The sync engine registers folders for inotify events, which should happen whenever a file changes/is created. Would you care to tell us what is your setup? What do you mean exactly with files which come in via rsync? Are you synching regular folders? or a network share? A log will confirm if MEGAcmd is receiving these file system notifications.

[srulikuk]

@polmr It makes sense that this is an issue with inotify, however I only have this issue in 1 dir/sync all the sub dir's here are named by date_time and contain a single tar.gz file 100-300mb in size, the other syncs do not have this issue (the files there are small 1kb-10mb)

The files are on a backup server and each hour files are rsync'ed to this backup server.

My setup is a Ubuntu 20.04.3 LTS server, the sync dir's are NFS shares however this should not really have any effect as this server is the NFS host so the syncs are local dir's.

as a temporary workaround I set the service to restart every 2 hours, however I would really like to have this resolved.

[srulikuk]

@polmr ^?
