Do you have ipfw or other firewall running?
Did you restart the network?

Hi All,
I have done some research ...
It appears that inn certain conditions, when the
net.inet.ip.fw.dyn_keepalive=1 (sysctl), remote clients or other
servers may not respond, and a new rule or dynamic rule is setup.
turning this to 0 seemed to help.
The effect (of having net.inet.ip.fw.dyn_keepalive=1) is that over
time, hundreds of FIN_WAIT_2 tcp states occure. With some software,
(vm-pop3d), it runs out of sockets, and I suspect the daemon does not
know how to hadle this.
So do a:
sysctl net.inet.ip.fw.dyn_keepalive=0
and in about 10 minutes all FIN_WAIT_2 's dissappear. (well almost
all).
I expect it virtually shut down dynamic rules too in ipfw, but I have
been reading more and more that people are saying don't use dynamics
on a busy site. Anyone care to comment.

Hi Grant,
I have set sysctl net.inet.ip.fw.dyn_keepalive=0. But both FIN_WAIT_1
and FIN_WAIT_2 does not seem to disappear. Even now, my squid proxy box
shows:
15 CLOSE_WAIT
5 CLOSING
2260 ESTABLISHED
2083 FIN_WAIT_1
829 FIN_WAIT_2
132 LAST_ACK
5 LISTEN
28 SYN_SENT
177 TIME_WAIT
1 been
Can you shed some light on this ?
Thanking you..
