             Summary: [0-8..0-91] Mishandling of message credit allows consumers to starve
                 Key: QPID-7387
                 URL: https://issues.apache.org/jira/browse/QPID-7387
             Project: Qpid
          Issue Type: Bug
          Components: Java Broker
    Affects Versions: qpid-java-6.0, 0.32, qpid-java-6.1
            Reporter: Keith Wall


The {{Pre0_10CreditManager}} mishandles message credit. In some circumstances allows message credit to fall beneath 0.  Once this has occurred, messages cease to flow to all consumers associated with the session (messages appear stuck on the queue).  Recreating the session (or connection) will allow messages to flow again.

This problem was reproduced on a 0.32 derivative but it appears the same issue will affect new releases too.
