Andrew Stitcher created QPID-4180:
-------------------------------------

             Summary: Occasional Buffer leak in qpidd
                 Key: QPID-4180
                 URL: https://issues.apache.org/jira/browse/QPID-4180
             Project: Qpid
          Issue Type: Bug
          Components: C++ Broker
            Reporter: Andrew Stitcher
            Assignee: Andrew Stitcher


Occasionally when running the tests with valgrind (make check) the stop_broker test fails
with a memory leak of one IO buffer:
