That’s quite a known issue listed in the Beta firmware 15.27:
As a new major version evolving through beta, there are a number of new, uncommon issues that may result in device reboot that we are continuing to investigate and work through. In particular, the Z3(C), MX84, MX100, MX400, MX600, MX250, and MX450 appliances have unresolved issues that we are tracking closely and continuing to investigate and drive towards resolution.
We need to take a customer to 15.10 (or above) for an upcoming deployment where we’re integrating their MXs with Umbrella. Anyone experienced this issue with MX’s reloading?
