Rebooted host, same deal…, ideas ?

The 5th host reboot was the charm…, no idea what the issue is

Same again, cannot update the supervisor…what the hell ?

It says its unhealthy. When you go to the supervisor panel you should see a “system is unhealthy” warning. What does it say when you click the link for more info?

It says nothing useful, random errors for the OS not running properly and some missing components. This is running on HA OS, so that’s not possible. Just have to hard reboot one or more times to get it going again. This now happens every time I try an do something using the supervisor
