My Unraid instance has been dying randomly for the past couple of weeks. Docker containers go down out of nowhere, WebUI becomes mostly unresponsive and ssh works but most of the binaries don't work. I passed a Memtest so i guess it's not ram. A reboot fixes it but not for long.

Enable the syslog server and post that after it happens again.

diagnostics get stuck on smartctl when it happens

here is a partial one after it get stucks, i suspect its the ssd because when i try accessing stuff on the ssd or docker it gets completely locked up

There's no syslog, see if you can copy that:

cp /var/log/syslog /boot/syslog.txt

here

syslog.txt

Unfortunately, there's nothing relevant logged, one thing you can try is to boot the server in safe mode with all docker containers/VMs disabled, let it run as a basic NAS for a few days, if it doesn't crash like that, start turning on the other services one by one, including the individual docker containers.

You can also try moving it to the array to rule out the SSD
