Memory leak [memory.world-caches.low-memory-trigger]

[FaanMaario]

Issue description

Since the new update of Genisys, my server constantly has these errors and crash strangely. I have removed all plugins to add them one by one to see if that was the problem but it seems not.

Steps to reproduce the issue

OS and versions

• Genisys: 25769c4 (from /src)
• PHP: PHP 7 with OpenSSL
• Server OS: Debian 8
• Game version: 0.15.6

To help us resolve this, you can create a memory dump when your server is at high usage and upload it and send a link.

How to create a memory dump:

1. Open your pocketmine.yml and set debug.commands to true
2. Run your server. You can use /status to see how much memory your server is using.
3. When the memory usage is near the limit, run /dumpmemory. This will create a memory dump in your server folder under /memory_dumps.
4. Compress the memory dump and upload it to a file host and post a link so that our developers can examine it.

Thanks for your cooperation.

[dktapps]

Something attempted to allocate 576 MB for a single object? WTF?

[FaanMaario]

@dktapps Yeah I'm surprised too.

[FaanMaario]

Here the dumpmemory folder I just created a minute ago @dktapps -> https://drive.google.com/file/d/0B1zyNGYeW8RRaUlNRnUyVmc5UE0/view?usp=sharing

Same here. I was experiencing a strange error in the past days: Genisys was not responding to any command input at console, players couldn't execute any command, no block updates, other players failed to join the server. The server kept freezing for about 10 minutes, then Genisys process was eventually killed by either system or itself. The freeze always happened suddenly when RAM usage seemed to be normal, main thread memory was only around 100-150 MB. The most mysterious thing is: No crash dumps generated. I used top in CentOS to observe the PHP process when Genisys froze: CPU usage approached 100% (98%-99%), RAM usage continuously increased until Genisys ate up all available memory.

Genisys version: 96940b834ebf8c4040cc453af5f01d5642987ac5 (By the way, the PHAR file I used was the one I produced using DevTools with source code on GitHub. Does it matter?) PHP: 7.0.3 with OpenSSL plugin Server OS: CentOS 7.2.1511

Because there wasn't any omen, I couldn't grab any memory dump. But this morning, after I decreased memory limit of Genisys, I successfully obtained 3 same crash dumps (Exactly the same excluding time stamps, server uptime and players online, even bytes tried to allocate was the same, 150994944.

[dktapps]

@leo3418 could you also provide a memory dump as per the instructions in my comment above? Thanks.

[Leo3418]

@dktapps I'll try, since crash may happen at any time without any sign of freeze.

[vzlomka76]

open pocketmine.yml and set cache-chunk = true

[Leo3418]

@vzlomka76 Thanks, but I tried and that didn't work. @dktapps Here's the memory dump I obtained. I don't know if it helps because it was grabbed when server was running normally.

[vzlomka76]

@Leo3418 strange, to enable this feature, I ate 30 minutes 5 GB of RAM. After switching on the 150 MB of RAM for 24 hours

[vzlomka76]

@Leo3418 and try to remove unwanted plug-ins and leave only the most necessary

[FaanMaario]

Now I have a different crashdump... That's very strange.

@Leo3418 No, I didn't touch the memory limit.

[ishitatsuyuki]

Do you guys have this option on? memory.world-caches.low-memory-trigger

[Muqsit]

@Leo3418 Can you use that world editing plugin that you have and fill a huge area? If that crashes your server, do respond.

[Leo3418]

@ishitatsuyuki Yes, it is already on. @Muqsit It worked well, tried just now, no crash. However I used the plugin for cleaning up players' building in the past week, after that crash started happened frequently. Is this the root cause?

[FaanMaario]

@ishitatsuyuki Yes it's on.

[ishitatsuyuki]

The cache should be destroyed if the option is on. Seems something should be wrong with it.

[Muqsit]

@Leo3418 Yes, it could be.

[FaanMaario]

Thanks for helping anyways. :)

[Leo3418]

@FaanMaario Try enabling check-movement in genisys.yml if it is turned off:

check-movement: true

[FaanMaario]

@Leo3418 Thanks :)

[FaanMaario]

I confirm that is due to the memory.world-caches.low-memory-trigger which is set to "on".

When I set it to "off", my server runs fine with no crash.

[dktapps]

The logic seems a little backwards, but it explains the crashdump.

[Leo3418]

Hmm, low-memory-trigger is enabled on our server, but there's no any crash since I turned on check-movement yesterday. The crash began when I set check-movement to false about 10 days ago, maybe it is (also) the cause of issue. I will do further investigation.

[SleepSpace9]

I also had many annoying crashes (without crashdump) with check-movement: false. Before the server closes the CPU is eating up over 100%. When I do "perf top" the absolute winner with the highest percentage is "zend_hash_index_find". I needed 3 days to figure out, that the check-movement setting was the cause. I think we need some further investigations. But because I didn't have memory problems this is probably not related with FaanMaario's issue. I'll open a new one and test without plugins etc.

[Leo3418]

Confirmed. On my server especially, when check-movement is on, everything's OK; when it's off, server keeps crashing. Today I turned off check-movement again, then those familiar crash dumps reappeared. I think it's also necessary to inspect code of the check-movement feature.

[dktapps]

Thanks for your contributions guys, these issues will be investigated.

[legoboy0215]

Mine is the opposite. When I have check-movement on 'on', the whole server takes up 100%+ CPU at times. When it is off, everything is fine.

[Nivek-C94]

Try disabling async chuck sending..stoped the crash for me a while ago. This might be a different issue though.

[Muqsit]

Any luck after the raklib update?

[dktapps]

@Muqsit That wasn't a leak fix, that was a fix for a DoS bug that caused slow packet processing. It won't make any difference to this.

[dktapps]

Is this issue still occurring? Seems tighter safety restrictions on the caches would be in order if it does.
