Try switching to Rocky Linux 8.x.

You can refer to the official documentation for the system requirements:

The official documentation mentions version 8.4 and above for the 8.x series. :rofl: Version 9.2 should be fine, theoretically.

It doesn’t seem very reliable, the difference is too big. How about trying Ubuntu 22.04 server? We haven’t had any issues using it.

If you have the resources and time, you can try 9.X to check its stability and other aspects…

The official recommendation is 8.X…

9.2 is already in use, now let’s observe it.
