For your kernel (all kernels above 2.2.11), you need to edit:

/usr/include/bits/types.h

The line is:

#define __FD_SETSIZE 1024

Change it to whatever you want. This is where Squid finds out what the
system limits are when configuring. Also you will need to set the shell
limits in the same shell you use for compiling like so:

ulimit -HSn 4096

The ulimit command also needs to be in your Squid startup script
(/etc/rc.d/init.d/squid on Red Hat) so that the limit is raised before
Squid starts.

You do not need to recompile your kernel...only Squid.

I think that's all you need to do. It's been a while since I've fought
with that problem. Hope this helps.
