Seems like the OS "malfunctions" after a few hours to a couple of days. The server is still responding to Pings, but services are all down, such as SSH. Doing a power cycle would make the system available back online, until it becomes non-responsive again. Moving back to 23.11.1 solves the stability issue. To add, I'm using a couple of instances for primary and secondary PiHole DNS servers.
Probably similar issue on this thread -
I'm a bit of a noob, if someone can redirect me to pasting logs. Can those be found on /var/logs as I haven't explored much. I have downgraded both my OPiOnes to 23.11.1 and Frozen the Armbian firmware updates, so I can't provide logs for now at least until I try to update one of the instances.
