One of my WAN interfaces keep flapping every <10 seconds, I simply cannot figure out why. I've already attempted to move it to a different physical port on the firewall, no change.
This is a sample of the logs:

This repeats every just under 10 seconds. I'm not sure what to try now...

Well, that was weird... I upgraded from 17.7.4 to 17.7.5 today and there's no more flapping...

Hi there,
This likely wasn't a solution in code, you probably restarted and now the system behaves differently until it doesn't?
Cheers,
