Open Stack

Thanks Robert,

Yes other components still work, openvswitch works fine as no flows are
dropped.
I even do not see any error in the logs, but still it stops working.

Also, after the restart it starts working fine,so I don't doubt the space
in rabbit message queue to be a problem.

Regards
Akshat
