Expected results: Qpidd when starting/stopping should not trigger any AVCs. Additional info:
It's detected that at least following two releases are affected: qpid-cpp-client-0.22-49.el6.* qpid-cpp-client-0.22-50.el6.*
Darryl, please assess.
(In reply to Justin Ross from comment #2) > Darryl, please assess. I installed and ran the r49 qpid-cpp-server and verified that the AVC errors are happening. I discussed this with some people in the #selinux channel on Freenode, who said it's possibly due to a leaked file descriptor and pointed me to an article [1] by Dan Walsh as a possible cause.

These AVC errors are also present on RHEL 7, and with qpid-cpp-0.30. Also the AVC errors occurs when upgrading/downgrading qpid.
RHEL 7 bz: 1218323
These AVC errors are also present on RHEL 6 and 7 with qpid-cpp-0.32.
on RHEL 6 qpid-cpp-server-0.34-1.el6.x86_64 (also with qpid-cpp-server-0.30-8.el6.x86_64) selinux-policy-3.7.19-279.el6.noarch (this should be currently available via regular channels) or RHEL 7 qpid-cpp-server-0.34-1.el6.x86_64 selinux-policy-3.13.1-30.el7.noarch selinux-policy-3.13.1-37.el7.noarch Restarting broker does not cause above mentioned and/or new AVC errors.
