Vera luup engine rebooting.

[stress nero]

After adding the sensors to vera edge I started to get random luup engine reboots i am not sure what i need to do to fix that issue. I am using RPI3 ethernet gateway. can one of u seasoned veterans take a look and see if i need to make any adjustments on the code side please. it also says controller did not repond under ALTUI.
