Well Our team is trying to run a dedicated server, but the problem is, is that our server keeps crashing, at least once a day when it’s filled. Soon as we get the server full, about 2 maps later, it crashes.
Running a team, and trying to recruit people is hard to do, when we don’t have a server to do it on, because it keeps crashing. Whats left is an empty server, that no one wants to play on. 
While I’m not good at figuring this stuff out, I’ve come here, in hopes that someone can shed light onto our troubling situation. Included is a picture of the console error that crashes the server:

Heres the servers info, if it helps. If you need anymore info, just ask, and I can get it for you.
Win2k Server Edition
P4 2.4 ghz
1.2 gigs ram
Thanks for any help you can shed.
