Description

We see an increasing number of sockets in CLOSE_WAIT status in our production environment in recent couple of days. From the thread dump it seems one of the Processor thread has died but the acceptor was still putting many new connections its new connection queue.

The cause of dead Processor thread was due to we are not catching all the exceptions in the Processor thread. For example, in our case it seems to be an exception thrown in configureNewConnections().
