Since some time my HAOS installation hangs. I cannot access it using the UI nor from the companion app. The only way to get it running is to power-cycle the Raspberry. It’s a large install (100+ Zigbee devices, some hundred automatons) that I’ve been successfully running 5+ years.
While the Ĺovelace IU is not accessible, I can access the observer URL as well as the web UI for AppDaemon.
This has occurred 1-4 times per week for perhaps 2 months and I’ve spent quite some time trying to track it down. I suspected my hardware, so I recently replaced the entire setup, now with a Raspberry PI 5 8GB with a m.2 HAT with a 1 TB NVME drive. It has been running really good 4 days and today it also crashed.
Some facts:
- Raspberry PI 5 8GB
- Pimoroni NVMe Base
- Kingston KC3000 1TB
- Core2025.2.5
- Supervisor2025.02.4
- Operating System 14.2
- Frontend20250221.0
- SONOFF_Zigbee_3.0_USB_Dongle_Plus_V2
- Tellstick Duo
One error I’ve found; unsure if it’s related:
/config/home-assistant-log-fault
Fatal Python error: Segmentation fault

This seems to be close to the issue described in https://community.home-assistant.io/t/never-seen-this-before-home-assistant-log-fault/849121
I’ve found other posts with issues seemingly close, but e.g. replacing the PSU does not seem to be a working solution for me, since I changed all hardware.
How do I best track this down?
