Public bug reported:

During scale tests (80 instances) a few instances created and their
status is ACTIVE (nova list/show) even though their TAP divices is DOWN
and they don't have an IP address.

Version - Icehouse with RHEL7
GRE+ML2 - All-In-One+ Compute node

Steps to reproduce:

1. Set Multiple RPC/API within neutron.conf 
2. openstack service restart
3. Create 80 instances - all Active and have connectivity
4. Delete  all 80
5. Create again  80
6. Not all instances (25) are ACTIVE as shown by nova commands.
