Heres a really good summary of what causes them and how to fix;

Do you have some WinNT boxes talking to your box with the FIN_WAIT_2's? There is a bug in NT's tcpip.sys which causes this. MS has a fix but you have to call them and beg them for it since it's not released. I got it from them and put in on one of my websites since I had so many requests for it.

fix is down at the bottom of:

Besides the NT fix this is also an indication of packets getting lost on the network so you might have your network guy look for errors and overfilled queues.

Supposedly there is also an hp patch PHNE_6875 which allows the fin_wait_2's to age out gracefully with a change in ndd. Our 11.0 does not have the patch so the option does not even appear in ndd.
