It should tell you in the logg why the port is err-disableing the port . Could be as simple as speed/duplex mismatches on the port if they are causing something like a lot of late collisions the switch will err-disable the ports . Check the switch and nic settings for these devices .

The log points to port vilation which it should as
it see a diffrent mac, but the real mac did not change, some how corruption has occured and the port has some how seen a diffrent mac? even thought no one has changed the device on the port.
