Hi, I have many users working on a web server. They executes among other things many scripts like php, perl or python... Some of them are strange, because they program a endless loop so they use more than 99 % of CPU -> That's pretty bad for the server ;-) For that time is the server unusable. I have always to login on Server via ssh and kill it. You understand that I am not able to watch my servers 24 h a day. Has Fedora Core 1 or Core 2 a function to manage that ? If a users of group is executing longer than 10 seconds, kill it with kill -9 or something like that. Thanks. Greetings!
