[jira] [Created] (DISPATCH-1579) Traffic hangs when multiple large messages are sent using different priorities

Ken Giusti created DISPATCH-1579:
------------------------------------

             Summary: Traffic hangs when multiple large messages are sent using different priorities
                 Key: DISPATCH-1579
                 URL: https://issues.apache.org/jira/browse/DISPATCH-1579
             Project: Qpid Dispatch
          Issue Type: Bug
          Components: Router Node
    Affects Versions: 1.10.0
            Reporter: Ken Giusti
            Assignee: Ken Giusti
             Fix For: 1.11.0


Create a two hop router network.  Attach a single receiver on one router.  Create 10 senders on the other router.  Each sender should sent a large number of (unsettled) messages at a given priority (IOW 10 senders, one sender sends priority 0 messages, another sends priority 1 messages, etc).

If the messages are large enough to trigger Q3 eventually most (all?) of the senders will hang stuck waiting for either settlement or deliveries to be forwarded.   There is no recovery.

I will post a reproducer soon.
