MTA Crash - 0xc0000005

[kecsmar]

Hey, guys.

I've been coding for 3 years now and I hopped in a very big problem, so I hope somebody can help me.

I am developing a server that runs with a RolePlay mod. I know what 0xc0000005 means, but I can't solve it.
I have a script that shows me all the script's CPU usage on server and client-side also.
Nothing runs more than 1-2%, expect the Inventory that can be 5% sometimes, but that's fine imo.

We have a lot of car mods, nothing is more than 15 megabyte all in all.
The server has 7050 megabyte RAM and 7850 MHz CPU for 50 players on average.

Everyone is crashing a day more than 10 times and I don't know what script or car can cause that.
I am using tables ofc, and I clear tables if the player doesn't have to use it on client-side.

I need some tips to fix this problem, have a good day.

At least show the crash dialog (for the one that most of your players get), so that we can get info like offset (not just exception code).

This crash is caused by running out of video memory.
https://wiki.multitheftauto.com/wiki/Famous_crash_offsets_and_their_meaning, Ctrl+F and search for 0x003C91CC.

Most likely some script creates textures (fonts, etc), but does not remove them when they are not needed. Or it does not check that some element already exists.

How can this be monitored:
There is a showmemstat command that displays the free video memory for MTA and how much is used by fonts, textures, RTs (+ Screen Sources);
There is a function dxGetStatus, which allows you to monitor this with a script.

How to know which resource is using a texture/font/etc:
2 options: the performancebrowser resource that allows you to monitor the performance in the browser and the ipb resource that allows you to do it directly in the game.
Then you need to select the Lua memory category and specify Client as the target*.
By columns DxFonts (= dxCreateFont), GuiFonts (= guiCreateFont), Textures (= dxCreateTexture), RenderTargets (= dxCreateRenderTarget) and ScreenSources (= dxCreateScreenSource) you can understand whether there is a memory leak or not.

*You can select any client only in the browser.

Yeah, but besides memory leaks that can also be a server with (a lot of) unoptimized scripts, models/textures. Usually a combination of unoptimized stuff.

If you want to learn more, join MTA discord and read the pinned post in #general (the one written by me), @kecsmar
