Hi Joe,

That ClosedChannelException appears to support your conclusion that
requests are being issued by the browser but blocking forever in the
server. That exception is saying that there is an http connection open
between browser and server at shutdown time (or at least the server
thinks there is).

Looks to me like somewhere within Trinidad's AJAX/PPR code on the server
a request thread is blocking waiting for a lock that never comes free...

If you send a "kill -3" signal to a JVM a list of all threads (with
stacktrace) is generated. It might be interesting to do that, and see
where the threads currently are. Any sitting inside trinidad or jsf lib
code when there *should* be no pending requests would be useful data..

Regards,
Simon
