[L4D2, Linux] Random Crash, No Error Messages

[nightsky30]

L4D2 crashed shortly after entering a match. There are two recent failure/crash reports listed for my system info. I believe the second probably deals with the L4D2 crash because it seems to have happened at the top of the hour.

I have no idea if this is the same issue I'm having with TF2 and RAM being filled to the point of game crash. It seems both games use the same engine. There were no errors given in L4D2. Boom! Desktop.
