After research, I found out, that the core is being generated as my CentOS box is running out of file descriptors. So my question here is, Is there any way to find out who (user/process) is polluting my server??
Please help

[hunter86_bg]

/proc/pid/fd shows how many file descriptors has the process (pid has to be replaced by process id).
Just find the process with most of them and take any action needed.
A bash loop should do the trick.
