I understand that I need to up the max number of open files in the linux

it's permanent?

I set to 16384. with about 100 clients this seems to be enough.
Best way to set it is in your local rc script (/etc/rc.d/rc3.d/*local)

How do you go about doing this on a RedHat 6.2 system? There
is an S99local file but nothing in it on setting maximum open
files.

I had to do this last week. On RedHat 6.2 put this at the end
of /etc/rc.d/rc.local:

echo 8192 > /proc/sys/fs/file-max
echo 32768 > /proc/sys/fs/inode-max

It increases file handles to 8192, you are supposed to have four times as many
inode handles as file handles so it increases those too.
