XG 135 random reboots

Hi

 

I have a XG 135 running SFOS 17.5.8 MR-8 and it has very recently started to randomly auto reboot during the day. It has happened twice now on two separate occasions.

All I can see in the logs is that the device has started, and no reason given for the sudden reboot, and all statistics eg under Firewall Rules have reset to zero?

Anyone else experiencing this?
