[CS:GO] Finding the source of memory leaks?

pcmaster · **Author**

Hello,

I am hosting a pretty popular CS:GO server and have noticed that every 1-3 days (varies), the server crashes.
After a look into the stack traces it turned out that it's unable to allocate any more memory (malloc returns NULL) and therefore exits.
This can be confirmed by looking into top before the server crashes - memory usage ~3GB (maximum for 32-bit apps).

Now, I don't know what plugin/extension could be causing this - is there a way to find this out?
I know that VProf exists, but afaik it only measures CPU stats?

Any help would be appreciated.

A good start would be trying to narrow down stuff. Maybe try removing some plugins or extensions?

Also, without knowing what plugins you are running, it's really hard to tell what could be causing the leak.

If you post the list of plugins that you use in your server, we can help you better in found the cause of crashes.

Also you can use this for found the cause -> https://forums.alliedmods.net/showthread.php?t=146644

Another option is restart your server one time in the day for keep it fresh. You can do it with plugins like this -> https://forums.alliedmods.net/showthread.php?p=907737

I am actually using Accelerator already, I have found the source of the crash with it.

Anyways, here the usual plugins/exts/version stuff.

I know that my SM version isn't exactly the "freshest" anymore, but I have the same version on my TF2 servers and they run 21+ days (and with even more connections) without any problems.

I see that you use some private plugins. Try to disable these plugins and only use public plugins that is know that works well. I think that maybe is possible that the first plugin in your list does not close the menu handles and this cause a memory leak. Also check your log errors for check if some plugins have errors.

Surely the solution is go disabling plugins to find the cause

I have disabled both the knife menu and GV (which produced errors), but to no avail.
Are there really no ways to somehow list the memory usage of each plugin with some sort of SM command/extension?

Interesting, only ~4.7MB of memory in use by plugins .. seems to be an SM/SRCDS issue itself.

I have 0 plugins on my server, that has memory leaks. But what it has enabled is GOTV. I run it at 128tick. Only servers with GOTV enabled, and record GOTV demos have massive leaks. Like after one game memory usage is from 1,5GB to 3GB
