Memory Leak with PocketMine V1.5 (Build #1258) lasting?

[ThomasMatthis]

Does anyone has the same problem? Crash happens 2-3 hours after Startup, in general:

Try lowering your memory or give priority to php and close all programs you use (sorry for my bad english)

[ThomasMatthis]

I reduced Memory to 512 MB (MCPE 1.4 worked fine with this configuration).

Moreover I stopped almost all other services on the server (except PHP).

Curios to see of this will solve the issue.

(Btw.: Don't worry about your english, I'm from Germany)

[ThomasMatthis]

Well, this one looks interesting: Tonight the error reported above occured again:

PocketMine-MP Crash Dump Thu Aug 13 03:24:24 CEST 2015 Error: Allowed memory size of 1073741824 bytes exhausted (tried to allocate 131072 bytes) File: /src/pocketmine/nbt/NBT__64bitLine: 148Type: E_ERROR

The interesting part is that I lowered the memory allocation before start-up in the server.properties to 512M:

memory-limit=512M

But the crash occured when memory consumption reached 1024 MB, in other words: Memory limitation in the configfile does not take effect anymore!

[shoghicp]

This is warned on startup, you have to set it up over pocketmine.yml. That config is deprecated

[ThomasMatthis]

Thank you, shoghicp!

I reinstalled the server from scratch. Is it save to use the memory default settings in pocketmine.yml, i.e

Global soft memory limit in megabytes. Set to 0 to disable

This will trigger low-memory-triggers and fire an event to free memory when the usage goes over this global-limit: 0

Main thread soft memory limit in megabytes. Set to 0 to disable

This will trigger low-memory-triggers and fire an event to free memory when the usage goes over this main-limit: 0

Main thread hard memory limit in megabytes. Set to 0 to disable

This will stop the server when the limit is surpassed

main-hard-limit: 1024

(My server should have up to 2GB free Memory available for the mindcraft process)

Regards

[ThomasMatthis]

Unfortunately a memory issue remains even with the new config:

Fatal error: Allowed memory size of 1073741824 bytes exhausted (tried to allocate 32 bytes) in phar:///hom
e/server/POCKETMINE/SERVER4/PocketMine-MP.phar/src/pocketmine/level/Level__64bit.php on line 1259 [22:30:26] [Server thread/EMERGENCY]: An unrecoverable error has occurred and the server has crashed. Crea
ting a crash dump

Only "progress" we made is that the crash took place in line 1259, now (instand 148). Actually the result looks not completely surprising to me, since with no proper configfile (pocketmine.yml) in place (like in the first case) the server should pretty much behave like a server which is set to it's default settings by it's default configuration file...

I'll try to get the crash dump from the server somehow even with no sftp at hand...

And here comes the dump (maybe with a viel reluctant LFs, but this is all my iPad mini can handle):

Search in pocketmine forum the ASR plugin. This plugin can help you because pocketmine always crash (i dont know why pocketmine is unnestable after 2-3 hours) with this plugin you can reload the server to get some memory for pocketmine and say bye to memory leak

[ThomasMatthis]

Thank you, SkygridRex, that looks like good advice! I'm gonna play around with the config (pocketmine.yml) first, like this:

Global soft memory limit in megabytes. Set to 0 to disable

This will trigger low-memory-triggers and fire an event to free memory when the usage goes over this global-limit: 1

Main thread soft memory limit in megabytes. Set to 0 to disable

This will trigger low-memory-triggers and fire an event to free memory when the usage goes over this main-limit: 1

Main thread hard memory limit in megabytes. Set to 0 to disable

This will stop the server when the limit is surpassed

main-hard-limit: 2048

Maybe this will get the memory management shoghicp implemeted to work and prevent the Server from chrashing...? Otherwise I'll use the ASR Plugin.

Thanks again!

[ghost]

Try with this configuration (maybe is better) memory:

Global soft memory limit in megabytes. Set to 0 to disable

This will trigger low-memory-triggers and fire an event to free memory when the usage goes over this

global-limit: 2048

Main thread soft memory limit in megabytes. Set to 0 to disable

This will trigger low-memory-triggers and fire an event to free memory when the usage goes over this

main-limit: 512

Period in ticks to check memory (default 1 second)

check-rate: 20

Continue firing low-memory-triggers and event while on low memory

continuous-trigger: true

Only if memory.continuous-trigger is enabled. Specifies the rate in memory.check-rate steps (default 30 seconds)

continuous-trigger-rate: 30

garbage-collection:

Period in ticks to fire the garbage collector manually (default 30 minutes), set to 0 to disable

This only affect the main thread. Other threads should fire their own collections

world-caches: disable-chunk-cache: false low-memory-trigger: true

network:

Threshold for batching packets, in bytes. Only these packets will be compressed

Set to 0 to compress everything, -1 to disable.

batch-threshold: 0

Compression level used when sending batched packets. Higher = more CPU, less bandwidth usage

compression-level: 8

Use AsyncTasks for compression. Adds half/one tick delay, less CPU load on main thread

async-compression: true

Experimental, only for Windows. Tries to use UPnP to automatically port forward

upnp-forwarding: false

debug:

If > 1, it will show debug messages in the console

level: 1

Enables /status, /gc

commands: true

level-settings:

The default format that levels will use when created

default-format: mcregion

If true, converts from a format that is not the default to the default format on load

NOTE: This is currently not implemented

convert-format: false

Automatically change levels tick rate to maintain 20 ticks per second

auto-tick-rate: true auto-tick-rate-limit: 5

Sets the base tick rate (1 = 20 ticks per second, 2 = 10 ticks per second, etc.)

base-tick-rate: 1

Tick all players each tick even when other settings disallow this.

always-tick-players: false

chunk-sending:

Amount of chunks sent to players per tick

per-tick: 2

Amount of chunks sent around each player

max-chunks: 192

Amount of chunks that need to be sent before spawning the player

spawn-threshold: 56

Save a serialized copy of the chunk in memory for faster sending

Useful in mostly-static worlds where lots of players join at the same time

cache-chunks: true

chunk-ticking:

Max amount of chunks processed each tick

per-tick: 0

Radius of chunks around a player to tick

tick-radius: 3 light-updates: true clear-tick-list: true

chunk-generation:

Max. amount of chunks in the waiting queue to be generated

queue-size: 8

Max. amount of chunks in the waiting queue to be populated

population-queue-size: 8

Use this configuration to reduce de memory use and bandwich usage

[ThomasMatthis]

Thanks a lot! My memory settings were ridiculously low, since I mixed up MB with GB!

[ghost]

If i understand, Do you set all values in GB? Example 1024MB 1MB

[ThomasMatthis]

Initialy I thougt all settings were in GB, so I wrote:

global-limit: 1

for instance, believing this meant 1 GB...

But for this case it should have been

global-limit: 1024

Don't worry, I changed the configuration now very similar to the configuration example you gave. And the server is still up and running after 12+ hours! :-)

Thanks again!

[ghost]

Do you have a public server? Because i can help you

[ThomasMatthis]

Mezzo Mezzo. Server is available through the Internet (VServer), but only used by me and a couple of kids. Therefore no heavy traffic and only a handful logins each day...

Thanks, again for your help, Diego, but I think I can get along at the moment.

And me and the kids just can't wait to get MCPE 0.12 into our hands... ;-)

[mattbisme]

I still seem to run into this issue daily. I have tried the suggestions in this ticket, but they only seem to prolong an inevitable crash. Memory never seems to clear itself at all, even after everyone has logged out of the server.

[ThomasMatthis]

It looks to me as if the configuration mechanism described above is sort of a workaround to deal with some kind of memory issue (in the version history one sees that they did a lot about memory management in MCPE V1.5). Even though the workaround works for me my concern is that the server might accidently set free some memory which is actually in use and, hence, corrupt the world. Therefore I followed the advice to install the ASR plugin and restart the server like every 2 hours to prevent any crashes!

[mattbisme]

The ASR plugin advises against setting the timer anything beyond one hour. Have you found it to be an issue?

[ThomasMatthis]

No problems so far...I think it depends on the configuration. My impression is, that the memory leak eats up apprx 150 MB per hour. So if you are running the server with only 256 MB allocated memory you should restart every hour...

[mcprostar205]

I've been experiencing memory exhaustion on Build 1258 for several weeks. Tweaking the pocketmine.yml has not helped. This issue occurs after several hours and typically when the server has very few or 0 players. I'm out of options but it is apparent the PHP process is not freeing memory...it just grows.

Btw, is this issue closed because it was solved?

Hi Scott, I don't think that the memory problem with Version 1.5 has been solved for real, but since there are workarounds to deal with the situation (see thread above, esp. regarding usage of ASR Plugin) and developers are already working on 1.6 I closed this issue. Regards Thomas

[mcprostar205]

Thank you Thomas for the confirmation. I might have found the contributor to memory exhaustion. I used GrabBag's "entities" command and discovered several hundred entities, especially mobs, squid, and villagers. After running "/entities nuke all" the memory appears to be remaining much lower. I wonder if you or others can confirm the same. If so, we can have the PocketMine team look into these entities that may be leaking memory. I'm sure if its not fixed in 1.5 that it will be problematic in 1.6. PM 1.4 was much more stable; hopefully we can help the PM team get a stable 1.6.

[ThomasMatthis]

That is valuable new Information, Scott. I could reopen the ticket to ensure the team gets informed. Problem is, that I wouldn't find time to give them any Feedback, if needed. Would you take care of this ticket then and answer any questions? Otherwise you could open a new issue with the newly found Information!

I did a little research at GitHub and twitter (@pocketmine) and I wonder, if anyone in the team would be interested in fixing the V1.5 issues at all. In the GitHubs' pocketmine repository there doesn't seem to be any V1.5 branch anymore (which is probably the cause for not having a stable V1.5 version, yet). And already on 07/14/2015 it got announced at twitter "@PocketMine: PocketMine 1.6 will support Windows 10, Android, iOS and Windows Phone players on the same server! Also in the future Java players as well". Sounds to me, that MCPE 1.6 won't have a common code base with V1.5, but will be a completly new piece of software...hence reopening this issue is probably helpless!

[mcprostar205]

Thank you Thomas. I wonder if the MPCE 0.12 branch is for PM 1.6? But you're right. I don't see a PM 1.5, although it really won't matter once MPCE 0.12 is out. My users will upgrade their clients and then be unable to play on PM 1.5 due to incompatibility. It will force the upgrade to PM 1.6. Let's see!

[mattbisme]

I recognize that with 1.6 on the way, this issue may or may not be relevant anymore, but in case that it is: I recently switched the my server over to Anvil worlds only. It has been running great since I abandoned the old MCRegion worlds.

Now, these new worlds do not have as many of the entities that @mcprostar205 mentioned, but I thought it worth mentioning. Memory usage is extremely low for me now. I no longer need to run ASR!

[ThomasMatthis]

Interesting! Do you know if it's possible to convert an existing MCRegion world into the anvil format with MCPE? Regards

[legoboy0215]

This is not a forum @ThomasMatthis

[mattbisme]

While I recognize that a question like that could cause a ticket to spiral off-topic, I do think @ThomasMatthis is asking something helpful. A map converter would be quite useful when determining whether or not the map format is related to the memory leak.

That said, I have invested many hours in trying to convert existing MCRegion worlds to Anvil worlds. Nothing I have found (even Mojang's own tool) has been helpful. I even asked about it in Pocketmine IRC channel where user @Intyre mentioned he might try to create a conversion tool (after his surprise that the Mojang took did not work). In the end, I used the WorldEdit plugin to copy over parts at a time.

If performance is format related, then conversion of an existing, problematic, MCRegion map would be very helpful.

[legoboy0215]

Ask in the forums then. A bunch of posts about that..

[ghost]

@legoboy0215 if you don't like answer the questions only go out (i dont like the people said this is not a forum and don't help the people)

[ThomasMatthis]

Thank you very much for your support, @SkygridRex and @mattbisme. Both of you have a point: If the memory leak depends on the data format used this is important information for the community esp. since many users most likely treasure their "old worlds" (like me and my son). And arguing that the issue is a big topic in the forums without offering the slightest hint where and what to look for doesn't meet the users needs. Nevertheless @legoboy0215 hint that this is a basically a bug tracking tool, not a forum, is kind of right, too.

I'm sorry if I caused any anger with my comments and if so I apology. Maybe we can meet everybodys needs by

A) providing a link to some related Information in the forums in order to complete this issue B) opening another issue in order to track @mattbisme observations?

Regards Thomas

@ThomasMatthis run your MCRegion world on Minecraft PC then you get a Anvil world

[ghost]

It's a theory not tested

[PEMapModder]

@SkygridRex You are recommended to use mcregion since it is faster.
