Duplicate IP address detected - Cisco CSS

Hello,

After I upgrade our 11506 CSS pair from 7.503 to 8.205 I have been receiving the following messages non-stop (changed portions of the IP and MAC with 'xx'):

x.x.138.6 - Circuit interface to the Server environment

Base Mac Address:  00-0c-xx-5f-d8-xx

I've verified that the 2 servers we're getting these messages for are not configured as a service nor any part of the configuration.  I also checked with our Server folks that they do not use our x.x.x.6 as a gateway for there servers.

Thanks,

Brian
