too many process

EAD · 05-02-2006, 04:42 AM

Hii, I have noticed a bug in linux, when I am making a program in C that do
Code:

while(true) fork();

and then run it on other host, the kernel get stuck after a while.
Is there a way to protect against it?
and sencond, after the user have disconncet, Can I kill all those process?
and third, How can I limit the cpu use of each user so no on will make the cpu too busy?
I need the answers as a "root" and also as a reguler user what to do.

check out ulimit to see how to restrict users and groups from taking too many resourses.

Look in the bashref manual.
Ulimit can limit the several resources including the maximum number of processes that a single user can use.

If the host uses pam, there is a pam_limits module that enforces user limits.

You set these limits by editing /etc/security/limits.conf
