I may have found the culprit after monitoring htop. "vnstat -n" process eats up CPU cycles, sometimes reaching up to "6+" load-average (even if this OrangePi is quad-core equipped) This only happens intermittently and I can't seem to find the pattern. Sharing my observations here: Only affects Linux 6.6.16-current-sunxi and higher (such as edge), legacy firmware is not affected (stable for more than a week) Installing Pihole with cloudflared DoH package seems to trigger high CPU usage of vnstat Reboot fixes it (or a power cycle) Having PiHole with dnscrypt-proxy does not trigger the issue (so far, this test instance is already at the 16-hr mark, will keep on updating uptime) Since it was stable overnight I now have two instances with this configuration, hoping for the best! Not sure if helpful, but this is all that I have for now. Thanks!

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.
