      Description

      Description of problem:
      While fencing nodes in a cluster, occasionally encounter an issue where a previously backup broker becomes deadlocked while deleting auto-delete queues. Only noticed the issue because 'qpid-ha promote' hangs attempting to promote a backup to primary.

      Version-Release number of selected component (if applicable):
      Qpid 0.18

      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
