is there a way to limit cpu resources for users, i have a game server and i want to be able to limit how much cpu the users use. i messed a little bit with the limits.conf but when it hits the cpu limit the server crashes, and i just want it so it dosnet go above that.

Also whats the best way to upgrade the glibc version, i heard if you do it worng it could really screw things up

Thanks
