Why is my Dell PowerEdge R740xd server experiencing high CPU usage on minimal load?
I am experiencing this consistently high CPU usage around 30% to 40% on a dell poweredge r740xd server with two intel xeon gold 6248 CPU. The server is running ubuntu server 22.04 LTS and is primarily used for mySQL database hosting.
I have noticed this issue for the past week. The high CPU usage persists even when the database load is minimal, and there are no other significant applications running. I've tried restarting the server, updating the OS and packages, and checking for CPU intensive processes using
top and htop without success.
Lemme attached a top output from a typical idle state for reference.

I suspect there might be a kernel issue or a hardware problem or maybe a resource hungry process that's evading detection. Any suggestions on further troubleshooting or potential causes would be greatly appreciated
