squid under solaris 2.5.1 consume a lot of file descriptors?

I have configured squid 1.1.20 on a Ultra Sparc with Solaris 2.5.1
recently. I notice that when the connection to outside is sluggish,
there will be a number of CLOSE_WAIT with child connecting its http

parent.8080 child1.4501 33580 0 8760 0 CLOSE_WAIT
parent.8080 child2.4428 17520 0 8760 0 CLOSE_WAIT
parent.8080 child2.4963 17520 0 8760 0 CLOSE_WAIT

* parent is the Ultra Sparc.

So, the number of file descriptors used increased a lot during that
period. It rises up over 1000 even when there are a few established
connection only. However, I seldom notice that there are any CLOSE_WAIT
in a squid parent proxy server under Digital Unix.

I would like to ask whether you have similar observation. If your proxy
server is busy enough, have you tuned anything such as
tcp_close_wait_interval of /dev/tcp? Its default is 240000ms (=4mins).
Thanks a lot for your opinion.
