Re: send hangs using vm://

Hello, I have an embedded AMQ with 2 clients using vm:// and tcp:// respectively.  The tcp://client mostly used to send lots of messages to the vm:// client.  The vm://client periodically sends control massages to tcp:// client.

The issue I am facing right now is the send operation from vm:// client hangs indefinitely when the broker in is under stress processing messaging sending from tcp:// client. It continues to hang when I stop the tcp:// client and all of its messages are consumed.

here is the stack trace

My configuration is a typical default settings.

is there a work around?  is there a way for me to set some timeout at ArrayBlockingQueue<E>.take() ??

Any help is greatly appreciated.
