Prevent server freeze by overload - linux

Question

Is there any application that prevents a linux server from freezing by cpu overload? Sometimes, by mistake, someone overload it by executing different tasks in parallel and it freezes the machine what causes a reboot need.

Thanks in advance.

Answer 1

You can limit the cpu available per user: take a look in /etc/security/limits.conf (read the comments in the file or use man limits.conf)

You can also launch ulimit -a to see what resource limits are in effect
