more fd's then the shell allows on freebsd?

Does squid set its own resource limits, or does it have to obey the
shell's max? I have a set of 4 freebsd 2.2.7 systems that are configured
with 30000 file descriptors available, however neither ulimit(1) or the
shells' builtin ulimit on the system will not ulimit themselves above 8192
fd's. Can I recompile squid and somehow force this limit up? I would
like to be able to set this to about 25000 fd's. I am already running
into occasionaly problems w/ the current limit of 8k.

TIA,
Peter
