Blank screen after some hours - breakpoint debug exception #50

Closed bergernetch closed 2 years ago

bergernetch commented 2 years ago

After a few hours, the screen turns blank (black).

The error message in dmesg is Unhandled prefetch abort: breakpoint debug exception (0x002) at 0x03658e54

docker-compose logs shows nothing.

I can restore it by running cd /home/pi/magicmirror/run && docker-compose restart

Could this be an error in Electron itself?

Never saw such an error before, there are 2 things you could try:

disable all modules one by one to check if this is caused by a specific module
increase shm_size in your docker-compose.yml e.g. to 256mb (see the faq)

I tried with a second Raspberry Pi, but it happened again. So I installed a fresh Raspian and the did a classic MagicMirror install without Docker. Now everything runs fine.
