Random Hass.io restarts


Hass.io superviser keeps restarting my system randomly. Initially i was running on RPI 3B+ and i thought that memory card or psu is the reason. Changing SD’s and power i ended up with hass.io installed in docker on Ubuntu server 18.04 on one of my computers.

And nothing changed - same restarts with Watchdog found a problem with Home Assistant Docker!

Any thoughts\ideas\fixes on this one?
