Host Flapping on VMware & Cisco

Our log file shows that we are getting the following error on our Cisco 6504:

Feb 2 13:31:34.096: %MAC_MOVE-SP-4-NOTIF: Host 00xx.00xx.00xx in vlan 111 is flapping between port Gi2/3 and port Gi2/4

Please advise on what is causing this to happen and how to resolve this issue?

What type of interconnects are you using on the enclosure?
