Re: A fork Bomb - A deadlock ??


A fork bomb is not a deadlock.
The kernel has a strategy for dealing with forks: It lowers the priority
of the parent as well as the child process. Still, fork bombs create
processes exponentially, and the system load increases rapidly, making
the system verry slow. 

You can configure the max no. of processes per user in
/etc/security/limits.conf (Donno why it never worked for me though;) ...
any ideas?


1) I had written a Fork Bomb Defuser kernel module. You can get it from:

2) If your kernel is configured with CONFIG_MAGIC_SYSRQ enabled, various
emergency functions are available via special <Alt><SysRq> key. Read 

Hope this helps,

Dont try this at Home! [ echo "$0 & $0 &" > ...;chmod 777 ...;./... ]
