Home Assistant keeps restarting. Help in analyzing log files appreciated

[swa72]

For the last couple of days I noticed that HA restarts randomly. The last time this night at 4 in the morning. I have studied the logs (both supervisor and home-assistant.log.1) but I’m lost how to proceed further.

The system has been rock solid for the last couple of months if not years, running the same SSD hard drive and power supply without problems.

There is a peak in CPU usage around 4 this morning but I reckon its due to the reboot.

Key data: core-2024.5.1, Home Assistant OS, python_version 3.12.2, 6.1.73-haos-raspi, Home Assistant OS 12.2, supervisor-2024.04.4, running Nabu Casa.

After the previous reboots , supervisor’s watchdog complained about 2 missed API calls and triggered a restart. But not in this one …

I’ll attach both supervisor and home-assistant.log.1 here and appreciate a hint on how to debug this further.

You did not say what hardware so I assume RPi.

How to Troubleshoot Raspberry Pi Crashing.

[swa72]

Yep, it is a Raspberry Pi 4. Thanks for the link. I think I’ve covered points 1-4 on that list, now I’m at 5 and seeking help in interpreting the relevant parts of the log files.

If one does not see any obvious stuff in the logs, I will follow the route outlined in 2024.5+: Tracking down instability issues caused by integrations - Community Guides - Home Assistant Community (home-assistant.io).

Power supplies go bad. Did you try another approved power supply?

[swa72]

Tried that already to no avail. I’m running in safe mode for a day now and have not observed another restart.

2024.5+: Tracking down instability issues caused by integrations

If you find your system unstable because of a misbehaving integration, there are a few methods for identifying and recovering from the problem. It is recommended to use Home Assistant’s built-in debug mode in conjunction with asyncio debug mode.

Using Home Assistant's built-in debug mode in 2024.5.x or later (preferred)

If you are using version 2024.5.x or later, Home Assistant has a built-in debug mode: <a href="https://www.home-assistant.io/docs/configuration/troubleshooting/#han…
