I also have the problem of ports sticking, but not
in FIN_WAIT2, they are in the state CLOSING with
recv_q = trans_q = 1.

As luck was to have it, my ppp link went down last
night due to a stupid config error on my part. But
the strange thing was that my kernel 2.1.10 started
to emit messages like

kernel: droping syn ack:10 max:10

which is of course expected. However, they never went
away even after the link came back up. After that,
I restarted sendmail, which stopped those syn messages,
but instead caused at least six message every 10s of the

Socket destroy delayed (r=0 w=288)

I had to reboot to cure the socket destroyed problem.

What should be noted though is that the system never
encountered any other problem. So it's nothing but
a syslog hog :)
