Hi,

Thank you all for you suggestions.
After updated the table fixed_ips and floating_ips, this problem was
eventually fixed.

I finally figure out how to reproduce this problem:
If an instance associated with a floating IP is terminated, the instance
can be successfully terminated, but the floating IP is also associated with
the deleted instance in database.

Also this is a known issue:https://bugs.launchpad.net/nova/+bug/997763

If someone can make a backport for Essex, that will be great.

Thanks,
Sam
