Hello, My l4d2 servers occasionally crash on map change. I've added -debug to the start line in order to get debug.log and hope that would point me the cause of the crashes but the debug.log file is not being created after the crash? Im not sure what im missing?
Im running servers on Ubuntu 14.04.3 LTS

You may need to set up the memory dump limit manually. Follow this:
https://developer.valvesoftware.com/...ng_under_Linux

When it crashes it will make a 'core' file and you need to use 'gdb' to open it.

Have you also tried updating sourcemod and metamod and the plugins you have installed?

Also chuck accelerator onto your server (Can help working out crashes as well):

Will try that thanks. No i havent try updating SM and MM myself but i know someone whos experiencing same type of crashes ( on map change) and is using almost same plugins and extensions and upgrading or downgrading of the SM or MM didnt help. Yes i came across the accelerator but as its been mentioned some where on this forum Accelerator doesnt work with OVH's kernel and i would need to change kernel in order to get Accelerator running.

just restart everyday server and no crash.

If crash continue, check plugins or extensions, i have fixed this issue with a reboot by day.

Grab the accelerator extension. It is much better than default debugger.

Yea, im considering doing that if i find no other solution.

As i have mentioned above this extension doesnt work with the kernel on my machine or i should say that the kernel has grsecurity and that is what prevents accelerator to work.

I'm not aware of what grsecurity is, but a local compile should fix the compatibility issues.

Aren't you looking for -condebug, not -debug?

-condebug - Logs all console output into the console.log text file.

I dont think that would provide my any helpfull data since i had HLSW running when the server crashed and didnt get anything usefull in HLSW console output.

Ok so it turns out that i was missing a lib, hence -debug wasnt working. I got debug.log file and it looks like this:

----------------------------------------------
CRASH: Wed Oct 26 14:29:00 CEST 2016
Start Line: ./srcds_linux -game left4dead2 -debug -nowatchdog -tickrate 100 -maxplayers 12 -ip xxx.xxx.xx.xx -port 27018 +map c5m1_waterfront +exec run04.cfg
End of Source crash report
----------------------------------------------

Any ideas why there is no information about what caused the crash?

Look for the 'core' file inside the root of the game folder (eg core.1111, this is the crash dump). I can send you an example of the process if you need

Open it up with gdb
