Multiplayer CTD Server/Object issue?

[SEE]

My game rarely Crashes to desktop as such, it usually Freezes and I have to Ctrl Alt Del to Desktop. Sometimes, I get the LE stopped warning box, sometimes I get a logfile with something in it. I use CTD in my posts to describe a 'sudden non useful functioning state'........there you go, SNUFS in future?......

I would still like to know if anyone else, who normally gets SNUFS, can go on Kampverband13 No1 server, shoot a whole bunch of AI for a couple of hours - and no SSAO + Shadows enabled or required.
