It appears you may have found one, yes.

Could you maybe run your test under valgrind and get a better idea
where the leak is? Also, when you get this information, could you
please create a jira report for it?
(http://issues.apache.org/jira/browse/qpid) Please attach your test
progam and valgrind report.

Thanks,
-Steve
