Rick, Thanks for the detailed analysys, I'll investigate it.
Vasily -----Original Message----- From: Rick McGuire [mailto:[EMAIL PROTECTED] Sent: Friday, January 25, 2008 1:56 PM To: dev@geronimo.apache.org Subject: Re: Hang on shutdown on Harmony I'm not sure I understand how this stack trace is occurring. Is it possible that there's an error in Harmony exception handling? Here's what's supposed to be happening here. At ORB shutdown, the socket that acceptor has issued the accept() call is closed. That's line 111 in Acceptor_impl. This should cause an I/O exception, which is what the stack trace is showing. However, there's a catch for that IOException at line 125 in Acceptor_impl that should be turning that into a org.omg.CORBA.COMM_FAILURE exception. That exception in turn should be caught GIOPServerStartedThreaded.starterRun(), which detects at that point that this is a shutdown situation and terminates the run loop on the thread. The loop that Jarek mentioned in ORBControl is waiting for the server threads to finish shutting down, but if that IOException is not getting trapped properly, this thread goes away without cleanuing up its state. I am a little puzzled about how completeServerShutdown can get caught in a loop, since it appears to have a cap on how many times it will go around that loop.
