ok. It seems there is a bug somewhere :-)
Can you again copy/paste this creating/deleting part of the node log and tell me
which is the correct bat0 MAC address of the node announcing the change?

E.g:
on fon-53 you have this log:

then go on node 5e:e6:fc:ae:55:a8 and write down its bat0 MAC address, please.
Moreover, is bat0 bridged with any other interface (e.g. bat0 + eth0 within br0?)

1 second is the OGM interval. It seems there is some inconsistency in the CRC
check which is done on OGM receive (1 per sec). In case of inconsistency the
node asks for an update. When receiving the response the node deletes the whole
table (in this case) and refill it with the information contained in the
response message.
