I had trouble thinking of a good summary subject for this question 8-/.
Basically, I was testing NFSv4 from a Solaris client. Evidently Solaris
does not tear down the TCP connection when the client is shut down or
rebooted, leaving an orphaned established connection on the server.
The problem I'm having is when the client comes back up, it tries to
reconnect to the server, but the server believes the connection is already
in the established state. Solaris always uses port 1023 as the source port
for the initial NFS connection, so it is highly likely if you bring the
system up and then immediately reboot it the server will already believe it
has a connection to the client.

As a workaround, you can use state-less filtering on port 2049.
I've seen a bug related to this inside Sun... I'll heave to look more
closely at it as it is starting to sound like a TCP bug.
