Hi,

A thread over on freebsd-net@ discusses a situation where
Linux clients seem to get stuck when the TCP connection
is partially torn down. (FIN_WAIT_2 on the client and
CLOSE_WAIT on the server.)
The thread is here:
http://docs.FreeBSD.org/cgi/mid.cgi?YQXPR0101MB0968FB1FF0FC481CE37E9A81DD649

Although the underlying cause is not known, I think that
the attached patch, which adds soshutdown(...SHUT_WR)
calls where the socket is no longer useful, might fix the problem/

If you have a FreeBSD NFS server (especially if you have Linux
clients) where you can patch the server, please try the attached
patch and let me know how it goes.
