I’m having similar issues with hangs on Hassio 0.113.0, and all my logs show no errors or anything out of the ordinary.
My Swap Use is hitting 100% and the CPU throttles up to between 60-80%. My Rpi stops working a few times a day and I need to pull the plug on the whole thing and reboot. I’m using an SSD via USB, so it’s not a failing SD Card.
All my Teckin wifi plugs connect to the Rpi, and if it hangs and stops responding then all the devices reset. The relays click and some devices turn on (!), such as a back-up light that kicks in if the UPS triggers.
I’ve tried disabling add-ons one at a time today, and the culprit looks like it might be InfluxDB ver 3.7.2. This updated today to 3.7.3 and didn’t restart, and during the period it wasn’t running the CPU stayed down at 8% and the Swap Use was down to 40%. A few minutes after it started back up, it went straight to 100% Swap Use and 80% CPU.
What add-ons do you use? Have you tried monitoring your CPU use and other Rpi parameters? Have you tried disabling add-ons?
