After a long, long period without any issues at all, I’m having periodic lockups of my HA instance. This is running vanilla HassOS (up to date) from a clean install onto a new uSD card (SanDisk “max endurance”, bought new one month ago when the problem started in an attempt to diagnose it) and my imported configuration, while tweaked a little, hasn’t changed too much over the last 6 months.
When it fails, it seems to just drop off the network and stops responding to pings. It always recovers with a power cycle and, at the moment, lasts for maybe 3-4 days before it fails again. It doesn’t always fail at the same time of day and I can’t get any pattern from it.
I would appreciate some suggestions on how to diagnose this as, when it last happened, I pulled the HA logs before rebooting, but they didn’t contain anything useful that might suggest why it had failed. The Pi4 has been a pretty good platform for me, but I depend on HA too much now, so if I can’t work out why this is happening, I might just have to bin the Pi altogether
Any suggestions, tips or assistance would be very much appreciated.
