Reproduce:
Deploy Centos HA, nova-network FLATdhcp, tagged interfaces, DEBUG=TRUE: 3 controllers, 1 compute

Issue:
- RabbitMQ is broken and won't start back, after reboot it starts but remains unoperational.
- None of the Openstack services start after controller node reboot
- 'heat list' hangs every the time after RabbitMQ was stopped for the 1st time.

Console actions and results:

*Pre-patched behavior*
