I don't recall exactly where I read it but I am pretty sure you don't want
to do what I 1st did and bump up the current too high - you will just
consume system resources. You can set _max to any number as that doesn't
consume resources until put in use. So what I did was, in the /etc/system
file, the following:
set rlim_fd_cur=2048
set rlim_fd_max=4096

Reboot (of course) and then when compiling squid, I *first* do a make
distclean (I lost a lot of time before Henrik reminded me to do that as the
older values didn't get cleared), and then run my own makesquid file. This
way I don't have to recall all the options I use and sets the ulimit's as
defined in the FAQ. So I have something like this in /home/adam/squid, then
cd to squidVERSION, and run ../makesquidconfig

#!/usr/dt/bin/dtksh
# makesquidconfig
if [[ $CACHE_HTTP_PORT != 99 ]]
then
echo " CACHE_HTTP_PORT needs to be set in your profile to port 99, like so:
CACHE_HTTP_PORT=99; export CACHE_HTTP_PORT"
exit
else
pwd=$(pwd)
squidprefix=${pwd##*/}
ulimit -n 2048
../configure --prefix=/usr/local/${squidprefix} --enable-dlmalloc --enable-as

From what I've understood (Henrik's many posts) you probably shouldn't be
compiling in dnsserver - just use your system's default DNS (i.e. I think
dnsserver is deprecated).
