Hi,

What this error means:
ether5: bridge port received packet with own address as source address SOME MAC probably loop.

I find “SOME MAC” on local bridge and try to change it. But after minute or two new same error in log with mac I just change.

In our experience, that problem is caused by damaged ethernets. The ethernet maybe working or not, but the symptom is always the same, it links either it has a cable pluged or not (I mean that the link led is turned on even if the ethernet does not have a cable pluged).

Of course you also have to consider a real loop in your network as a possibility

Good Luck
