Description of problem: Spontaneously, I couldn't fork() (well, clone(), when running an external program from a running bash) as my user or setuid() (when running su) to my user anymore. The system calls return EAGAIN which indicates it runs against RLIMIT_NPROC, but this can't really be as there are only a couple of processes running (about 20, both soft and hard limits are 8191 on that machine). When I kill all processes of that user on the machine, things are back to normal. Maybe something corrupts the RLIMIT_NPROCS setting. Version-Release number of selected component (if applicable): kernel-2.6.10-1.737_FC3 kernel-2.6.10-1.741_FC3 How reproducible: Sometimes Steps to Reproduce: ? -- If I experience it again, maybe I can find a apattern, but I'm not sure about it now. Actual results: clone() from user, setuid() to user fail with EAGAIN. Other users are fine. Expected results: clone(), setuid() work
