> How reproducible:
> Rare (race condition)
> see also: https://bugzilla.redhat.com/show_bug.cgi?id=889552
> Steps to Reproduce:
> 1. Start HA-enabled brokers
> 2. Create tens-of-thousands of auto-delete queues
> 3. Fence / power-cycle the node hosting the primary broker
>
> Actual results:
> Occasionally the backup broker deadlocks
> Expected results:
> The backup broker does not deadlock
