I am runninf HA on Rpi 4 since mid december 22, and last month or so I am experiencing this same behaviour, random crasehes, sometimes after a week, sometimes twic in oe day, alway I find evrything umresponsive and Aragon fan at full speed, I need to power off and on to make it work again.
I have my RpI in Aragon case with active fan, conbee II and SSD on USB.
Where can I find logs tat might help to identify the issue?
I have the same setup as yours, and I’ve been experiencing the same issues since two weeks ago.
I had three crashes since this Friday, and every time I had someone manually unplug and plug the RPi back in to solve the issue (I’ve not been home for some time now).
The crashes happen at a completely random time and there is no sign of any memory leak prior to the crashes that may have been able to cause them
Is there any way to keep the logs after a system restart? The only way for me to fix the issue remotely is to ask someone to manually restart the system, and after that all the logs are long gone, so there are no clues for me to follow.
I changed the power source and it seems to solve the problem.
did you ever find what was causing this? I have exact same hardware, Pi4 4gb, ssd sonoff and Bluetooth on powered supply, pi4 is canakit re-branded with their PSU, it’s been happening for almost 2 years now, once or twice a month, changed PSU didn’t help, everything else looks normal. Was trying to download journal logs that doesn’t get erased but wasn’t able to do so
