Hello!
After upgrade to 6.6 log is constantly flooded with message “system, info - address changed”
What does it mean? How to get rid of it?
Screenshot from winbox is attached
Help, please. The log is completely useless now 
Well, does it really changes or doesn’t?
Could you post export of your configuration (mask public ip and/or other sensitive information)?
Regards,
M.
Here is my config
