Keith Wall updated QPID-7387:
-----------------------------
Description:
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 newer releases too.
