The Industrial Raspberry Pi Forum

I'm running a Python3 program on the RevPi Core3. After running for hours, my program apparently stops running, and the following is printed to the console (via SSH). I see similar content in kernel.log. I updated my system using apt-get update then upgrade, but this didn't help. I have no idea how to address this issue, so any help is much appreciated.

Update: I found a bug in my app that was causing a loop to run as fast as it could and therefore consuming most of the CPU time. Since I've corrected this bug, I've not seen this problem. There may still be some bug or vulnerability in some part of the system, but for now I am avoiding it.
