max child process number on Unix

[Victor Bao]

Is there a limition for maxmum child process number that one process may have at one time ?
I don't think there is one, but still want get some confirmation.
Thanks a lot,
Victor

Not exactly but there is a limit to the number of processes for a common user id (UID) and that is maxuprc which defaults to 75 but can be increased. This would have the effect of limiting the number of child processes unless a setuid() were done.

Hi Victor,

One limitation for non-root users would be
maxuprc (Max # of User Processes)

And of course there is
nproc (Max # of Processes)

Rgds,

and of course there are threads...

And of course if the maximum PID number is set to 30000, then you have a real limit, 30000.
