Hi Greg,
It was too hard to follow close sequence for me.
So decided to just add my own monitor bean that checks and logs
QueuedThreadPool's idle/total/max threads.
I hope this log and netstat results would make this clear.
Thanks,
Takenori

Ssl is a little complex in Jetty-8, specially when it comes to
closing, so there is a chance that a thread can become blocked during
the close conversation in jetty-8.
SSL has been entirely rewritten in Jetty-9 and what's more is fully
asynchronous, so that a thread will should never block in close.
However, the caveat in this is that we have seen some JVM issues where
close is blocking even for non-blocking channels.
cheers

Hi,
I have a case that CLOSING state socket remains.
And I wonder if this could have led to long latency in Jetty.
For example, as more and more CLOSING state sockets get piled up,
and reaches to maxThreads, then new requests won't get processed
until they are cleaned up.
So, when does a Jetty thread become idle, exactly?
If it is soon after sending FIN, CLOSING state won't be an issue.
I have looked through the source code,
also like bug 364921, but didn't get any clue.
Can you suggest where to look at?
My environment:
Jetty8.1
JDK6
SslSelectChannelConnector
Thanks!
Takenori
