1 The MessageingPostOffice need a readwritelock to handle msg,such as route,binding,removeBinding. 2 Once find a route,get readwritelock,it is using MessagingQueue to handle the msg(Delivery handle(DeliveryObserver observer, MessageReference reference, Transaction tx)). 3 while handdling msg,the Correspond MessagingQueue require a lock to deliver msg. 4 Then using RoundRobin policy choose one ServerSessionEndpoint to deliver msg by Remoting's bisocket.The serverSeeionEndpoint synchronize the method of handleDelivery.
The question is that,one thread hung at step 4 due to no tcp buffer(4557 port recv window is zero) to write bytes.The other thead need a lock to process bytes on port 4557.It is the reason of deadlock,if not using bisocket may resolve the problem?
