Hi guys. I'm running three game servers with SRCDS, and keep getting errors from each one. The error is a segmentation fault, which I don't understand. So what I'm asking is, do you know if this has anything to do with Xubuntu, where it may be putting the HDD to sleep? I'm moving to a server version of Ubuntu soon, with a brand new server, so it should be fixed. In my SSH (Using Putty in Windows 7) I sometimes get "(unreachable)" (without quotes) just before saying the directory I'm in at the beginning of each line.

Do you know how this could be happening or could be fixed?
I'm willing to provide more info, just ask.
