I did the ulimit -n 3000, but still get:

checking Default FD_SETSIZE value... 4096
checking Maximum number of filedescriptors we can open... 256
WARNING: 256 may not be enough filedescriptors if your
         cache will be very busy. Please see the FAQ page
         http://squid.nlanr.net/Squid/FAQ/FAQ-11.html#filedescriptors
         on how to increase your filedescriptor limit

even though the system reports:

constellation:/usr/src/squid-2.0.RELEASE# ulimit -a
core file size (blocks) 2097151
data seg size (kbytes) unlimited
file size (blocks) 1048576
max locked memory (kbytes) unlimited
