RPI crash/reboots if openluup running

My Raspberry 1
Keeps crashing and reboots with no log entry once openluup is running for some time,

The reboots apear to be randomly, so im not sure if its script related.

Openluup stating via rc.local as root under lua 5.1

The logs simply stop abd it reboots with no indication.

I’ve not seen this myself. I don’t know of any mechanism whereby a piece of pure Lua code could do that. I’ve had systems running for months at at a time, so I would look at your system configuration, perhaps hardware, or other apps, if any, for the source of the trouble.
