I had a server's CPU peg this morning forcing us to reboot the machine. I was able to reboot from the OS cleanly. The software that monitors CPU usage tossed it's warning at 9:26 AM. Looking through the logs, I don't see any errors or warnings.
Looking at the Resource Monitor - I see normal CPU usage, which for this machine is very minimal - typically under 10%. But the "Maximum Frequency" field is running at over 100% - it never drops. What do you make of this?
