CPU utilization messages

Hi, We are using F5 LTMS 2000s (11.2.1 Build 862.0 Hotfix HF2) and we are receiving the following logs after every 5 minutes on F5.

www notice chmand[6602]: 012a0005:5: Cpu utilization over 300 seconds is 100%, exceeded log level 80%

But when I checked the Dashboard It gave the normal CPU value. Kindly help me why the F5 show this type of behavior.

Waiting for the replay. thanks
