This past Sunday, April 12th starting at 2:20am and continuing to 12:45pm (about 10 hours) I received well over 8,000 emails from the controller about radius server unreachable events. These are scattered across nearly all of our APs (411 total) which are located in 6 separate buildings, attached so 22 different switch stacks. These email stopped Sunday afternoon. I then opened a ticket with Ruckus on this. Working the ticket now, no resolution yet
