A loop is happening somewhere in your network, causing the MAC adressess mentioned to be seen in rapid succession on PortChannel and then on a physical interfaces.

This can be caused by EtherChannel misconfiguration.
Can you post the configuration of the ports and of the EtherChannel on both switches, as well as the output of the "show etherchannel" command and of the "show interface trunk" for the ports involved in the EtherChannel?
