             Summary: Deadlock on publish
                 Key: QPID-7317
                 URL: https://issues.apache.org/jira/browse/QPID-7317
             Project: Qpid
          Issue Type: Bug
          Components: Python Client
    Affects Versions: 0.32
         Environment: python-qpid-0.32-13.fc23.noarch
            Reporter: Brian Bouterse


When publishing a task with qpid.messaging it deadlocks and our application cannot continue. This has not been a problem for several releases, but within a few days recently, another Satellite developer and I both experienced the issue on separate machines, different distros. He is using a MRG built pacakge (not sure of version). I am using python-qpid-0.32-13.fc23.

Both deadlocked machines had core dumps taken on the deadlocked processes and only show only 1 Qpid thread when I expect there to be 2. There are other mongo threads, but those are idle as expected and not related. The traces show our application calling into qpid.messaging to publish a message to the message bus.

This problem happens intermittently, and in cases where message publish is successful I've verified by core dump that there are the expected 2 threads for Qpid.
