After the update was applied tonight the server keeps restarting randomly. It happened ~5 times within 30 minutes. Otherwise, server is awesome. Thanks guys.
This is what steam says they fixed in that update......I call them liars and say they broke what is listed:
"Source Engine Changes (CS:S, DoD:S, TF2, HL2M)
Fixed an OpenGL crash for Mac players
Fixed several crashes related to Alt-Tab in fullscreen mode on Windows
Fixed client crash caused by invalid mesh
Updated shared interfaces to support the new Replay feature in TF2
Counter-Strike: Source
Updated the localization files
