Bug Description

Eucalyptus 2.0. Natty 11.04, Lucid 10.04 image for instances

I have a small UEC setup (1 Front-End, 2 NC), and at various points, instances running on each of the node controllers will lose their public IP addresses. I can re-associate available IP addresses from my pool (Managed NO-VLAN) with the instances, but this is a repeated issue. FYI -

Looking at the cc.log file we see that instance i-357C06B6 and i-45DC0806 have received a termination request however nobody was working on the servers at that time.

What component would trigger such a request?
