%RTD-1-ADDR_FLAP: GigabitEthernet0/2 relearning 5 addrs per min
Receiving this error message in 4 different switches in the same switch closet. They are not clustered together:%RTD-1-ADDR_FLAP: GigabitEthernet0/2 relearning 5 addrs per min. Debug ethernet-controllers address shows many additions and deletions on the trunk ports going back to the core. I also show the same mac address learned on different gig interfaces (say gig 0/1 and 0/2) and on different vlans (see attached). Any ideas on next steps to resolution?

Got any wireless or VPNs that could be an unmanaged loop?
Make sure Spanning-tree is up everywhere.
Start looking around for some user with a switch/AP under their desk.
Maybe one of your switches lost their trunking configs .... so now segments that used to be different VLANs are actually dumped into one big happy VLAN (i.e., have you added a new (Cisco) switch to the network recently?
The old "adding a new (unconfigured / non-VTP-configured) switch and having the latest VTP serial number push the (non-configuration) config out to all of the other switches on the net" thing come to mind (all/some of your VLANs went away).
