Upgrade to 2023.6.x and crashes

Hi there

I upgraded to 2023.6 (initially .0 then to .1 and .2 as released) and the system only lasts about 12 hours before becoming inaccessible. (No web connection, no app connection, no supervisor webpage). Was running fine prior to this.
I’ve checked and sanitised my recorder logs, problem persists.

Running home assistant on an Odroid N2 with external SSD connected over usb via a dedicated hub for power. To get it working again I have to power down the SSD and HASS then reboot.

Nothing obvious (to me) in the logs (then again if there was I wouldn’t be posting like this!).

Does anyone have any suggestions please?
Thank you!

Check cpu and memory usage. Maybe system run out of memory or something is triggering high cpu usage.

Sorry for the delay, had to add the system monitor then leave it to crash again.

Processor/memory all idling at crash time. Only error I get is:

2023-06-27 22:31:41.586 ERROR (MainThread) [aiohttp.server] Error handling request

I do use https and it has worked fine since I set it up - has there been any changes with duckdns/HA in the latest setups?
