Greg,

IMO, this qualifies as a bug.

To debug what's causing this scenario is your case, I would suggest
checking the database connection setting in nova.conf on your Compute &
Controller host. AFAIK, it either means Compute's status is not being
updated (Compute service down) or its being updated in a different database
server.

Hope it helps.

Regards,
Unmesh G.
