Crash dump files are empty

[Blah]

Hey, whenever my dedicated garry's mod server crashes (crashes are quite random), it says that crash dump has been saved to /tmp/dumps, however those crash dump files are empty. 0 bytes.
Is it necessary to put some command to launch script so that crash dumps are saved? Any idea?

Specs if matters:
Server OS: Ubuntu Server 12.04 LTS
Processor: AMD PHENOM II X4 960T 3.0G
Ram: 8gb
Game(s): Garry's mod and CSS for content
Start Up Command: ./srcds_run -console -game garrysmod +maxplayers 25 +map dm_island18_night -autoupdate -debug
Admin Mods: ULX + Sourcemod (for country filter only)

[Blah]

There forums are just wayy too dead :/

I gues I'll have to ask for help somewhere else.
