Holy crap.... thanks, Sean. This exact thing has been adding headache to my already big woes concerning certs with the 4.1.3.1 -> 4.1.6 upgrade.
I've been trying to do the recommended cert juggling bring it all back, but one unit in our CAS HA-pair decided not to play on the network. It was there, had link and everything.... but just wouldn't respond. And since it was alive via the heartbeat, this confused the hell out of the active member of the pair. The 'clear-arp' worked ... but I'm surprised that's necessary... this problem has been going on for days! If you have more information about that bug, I'd certainly like to read up on it.
