Red Hat very strange

To increase max open files for the whole system add the line
"fs.file-max = <# of open files you want>"
To /etc/sysctl.conf and then type sysctl -p to activate it. That should
be all you need, but if you feel the need to increase the per-user limits
on open files edit /etc/security/limits.conf and add
"<user/group/*> - nofile <# of open files you want>" and then when you
open a new user session that user will have the new limit.
