What I do is something different. I put this in /etc/initscript:
# Set # of fd's to 256 for all processes.
ulimit -S -n 256
That sets the soft limit for all processes to 256 fds. It can be raised
by an individual process if needed. My /etc/init.d/squid script contains:
MAXFD=`ulimit -H -n`
if [ "$MAXFD" -gt 1024 ]
then
MAXFD=1024
fi
ulimit -n $MAXFD
So this way, the number of file descriptors for squid is 1024 max, but
for all other proceses it's limited to 256.

That's a nice box. But don't expect any extra performance because it's
a SMP machine - squid is one monolithic process and will not benefit from
a second processor.
32 GB cache and 512MB of mem sounds about right for squid, you could do
with 256 or 384 MB if you'd run squid-novm (but squid-novm uses a lot
more file descriptors).

Don't worry - we have exactly the same setup (only 9GB of cache tho')
and it hasn't crashed ever. Except for the libc6 problems, but these
are now solved. I sacrificed myself as guinea pig when the box was
still installed here locally, and I think all bugs are gone now.
