Hang on map change

[BehaartesEtwas]

any plugins? -> try without any

running game servers inside a VPS is usually a bad idea. I wouldn't think it causes hangs on map change, but one never knows...

nice doesn't help much (if anything). try to set the server to realtime scheduling (see my kernel howto linked in the signature and look for the resched.sh there. ignore the rest, you cannot change the kernel)
