Pi Zero W loses connectivity periodically

Help Community Help

I have installed Pihole on the latest version of Raspbian on a Pi zero W. After running for between an hour and 10 hours, the Rpi hangs. The power light is on but I cannot access the Pi using a keyboard, ssh or the web interface. The install of the OS and the Pihole software is completely standard.

I have changed the SD card and the Rpi board and the problem continues. I have tried increasing the swap file size but again the doesn't help. I have tried changing the power supply (both standard RPI "official" adapters. and again this make no difference. I have tried installing the Pihole software at least 4 times.

I have installed Pihole in exactly the same way on a Rpi 4 and the system works perfectly.

Any suggestion on how I can resolve this issue would be gratefully received.

I think the following might be relevent.

Expected Behaviour:

That the Pihole should work for extended periods with out issues

Actual Behaviour:

The RPI hangs appears to hang after an unspecified period

These are OS level errors. I would research the Linux forums for solutions to this problem. If the underlying OS will not run continuously, Pi-hole will also not be available continuously.

Your Pi-hole debug log is normal.

I also moved this post to the Community Help category.

I will investigate further but these errors only seem to occur after I have installed Pihole.
