Does anyone know of any memory leaks in the
netfilter code?
I have a dedicated dual 667 running as a SNAT server.
It has two Intel Pro100S adapter. This is a RedHat 9
box. I am running kernel version 2.4.20-8smp. I know
it is not as current as what it should be. This is a
production box and have not had the time to upgrade the
kernel. I have noticed a steady decrease in the amount
of memory being utilized.

I am not positive that netfilter is the cause for
the memory loss, but it is the only purpose of the
machine. In the last 12 hours, the amout of
available memory has decreased by 1.5MB. I know
that isn't much, but since this is a production box,
I would rather not have to reboot it constantly.
