> I am running a Java Client against a cluster of 3 interior routers connected
> to each other. 2-way SSL is enabled for all the connections.
> There were 20 simultaneous queues with 20 senders on each queue and each
> sender publishing 1000 messages. All the senders were connected to Router 1.
> 20 receivers were connected to Router 2 with 1 receiver receiving from each
> queue.
> In the first run, router stopped receiving incoming messages after delivering
> 386,339 out of 400K "Hello World!" messages.
> In the second run, 388,781 messages out of 400K were delivered.
> I reduced the number of queues to 10 (halving total number of messages to
> 200K) and the issue occurred again.
> I ran the Java client on an 8 CPU machine again with 10 queues and the issue
> occurred again after delivering just 54K out of 200K messages.
> All the senders were hung (still connected) with no messages flowing at all.
> Connection information from qdstat:
> When the messages are flowing properly and I run "qdstat -c", I see all the
> senders as secure and authenticated.
> After they hang and I run "qdstat -c", it erroneously shows all the clients
> as insecure and unauthenticated.
> Shortly after the clients hang, all the queues are deleted from the router
> network but connections are still shown until I terminate the clients.
> I saw this erroneous situation before also when "qdstat -c" showed some
> senders as secure and authentic but some as insecure/unauthentic.
