[Openstack] out of fixed-ips!

Hi all,

I'm having an odd issue where I can't spin up new VMs; the error is
below. I've confirmed that the tenant starting the instance has
sufficient capacity.
I have another tenant who is running a similar number of VMs and it's
not having the problem.

This is ubuntu 12.04 running grizzly.

Any thoughts?  I assume that something in the DB is wedged ...

Thanks
JR
