Diagnosing HA Intermittent Stop

My HA system has a habit of just stopping intermittently and I’m trying to diagnose what’s happening. It happens about once a week and I can’t determine why but everything just stops working.

Is there a failure log I can look at to know why it stopped.

Running on an old Intel NUC

OS Version: Home Assistant OS 13.1
Home Assistant Core: 2024.9.2

Thanks.

The current log is config/home-assistant.log. That file is rotated to /config/home-assistant.log.1 on restart.

Thanks @nickrout - I learned a(nother) new thing about HA today.

Checked the logs and nothing but a bunch of deprecated function warnings and a couple of ValueErrors.

Any one have any ideas about what might cause these intermittent stops? Or where to look for clues?
