My cores seem to go south with flashing green every 21 days or so. I typically don’t see this happen but I’m running long term tests and it’s happened 3 times. Rebooting the core does not correct the problem. It happens around the same time on all of my cores.
Rebooting the WiFi access point corrects the problem. After a AP reboot the cores recover on their own and resume normal operation.
Does anyone have any ideas as to what I should look for?
