Last modified: 2017-02-23 14:45:58 EST
Description of problem: As part of investigation into https://bugzilla.redhat.com/show_bug.cgi?id=1264509 it was identified that qdrouterd was persisting in attempts to use connections from the satellite to the capsule which were no longer open on the capsule side. Upstream issue https://issues.apache.org/jira/browse/DISPATCH-144 was opened to track this work Version-Release number of selected component (if applicable): qpid-dispatch-router-0.4-7.el7.x86_64 How reproducible: 1/1 attempt Steps to Reproduce: 1. Use iptables on capsule to drop all port 5647 traffic to and from the satellite 2. Allow the existing ongoing connections to die off on the capsule side. I left mine running in this state overnight Actual results: qdrouterd persists in using connections which appear to be open on from sat -> capsule, which are no longer connected on the capsule as the capsule client has already torn them down. Expected results: qdrouterd tears down connections which are no longer operating and replaces them with new connections. Additional info:
Verified on Satellite-6.1.0-20151006.0 In and Out connections on 5647 dropped for an entire night then brought back. Was able to install and remove packages with no errors.
