Bug 878638

This BZ is descended from BZ 872934.   The former BZ caused a SEGV - that is fixed.

Now the problem is that the test framework reports a failure during the test teardown.

I believe that this problem is benign but irritating.  Here is what I think is happening:

  1. during test teardown, the cluster's queue is destroyed.

  2. one of the brokers in the cluster gets another message to the queue very shortly ( a few hundred microseconds ) *after* qpid::broker::QueueRegistry::destroy has been called, and the queue registry has been emptied.

  3. That broker throws an error because it sees an attempt to deliver to a nonexistent queue.

  4. The testing framework sees the error, and becomes upset.


I don't think that there will be a reasonable way to fix this in the C++ code.  I think the fix will either be in the testing framework, or in the test itself.
