I have checked in a fix for a race that would lead to these symptoms as r946106. I believe this fixes the issue, but as reproducing is very difficult and time consuming it is hard to verify. I'll mark this modified and we can re-open if it re-occurs.
The issue has been fixed, tested on rhel4.8 / 5.5 i 386 / x86_64 on packages: python-qmf-0.7.946106-3.el5 python-qpid-0.7.946106-1.el5 qmf-0.7.946106-1.el5 qmf-devel-0.7.946106-1.el5 qpid-cpp-client-0.7.946106-1.el5 qpid-cpp-client-devel-0.7.946106-1.el5 qpid-cpp-client-devel-docs-0.7.946106-1.el5 qpid-cpp-client-ssl-0.7.946106-1.el5 qpid-cpp-mrg-debuginfo-0.7.946106-1.el5 qpid-cpp-server-0.7.946106-1.el5 qpid-cpp-server-cluster-0.7.946106-1.el5 qpid-cpp-server-devel-0.7.946106-1.el5 qpid-cpp-server-ssl-0.7.946106-1.el5 qpid-cpp-server-store-0.7.946106-1.el5 qpid-cpp-server-xml-0.7.946106-1.el5 qpid-java-client-0.7.946106-3.el5 qpid-java-common-0.7.946106-3.el5 qpid-tests-0.7.946106-1.el5 qpid-tools-0.7.946106-4.el5 -> VERIFIED
