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 form:
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.
