Open Stack

What release were you running before Icehouse?
I’m curious if you purged/deleted queues during the upgrade.
Might be useful to start fresh with your rabbit, like completely trash your mensia during a maintenance window (obviously with your services stopped) so they recreate the queues at startup.
Also, was kombu upgraded along with your openstack release?

The new one and the phantom old one. This then leads to messages piling up in the unacked queue. This feels like a rabbit bug to me but just thought I’d mention it here too.
