Abnormal CPU usage after upgrading BIG-IP 2000s to 11.5.1 H3

Hi, I've a lot of spikes in system CPU usage after upgrading to 11.5.1 HF3, actually I have one spike every 10 mins, and those spikes are in range between 50-80% although I don't have any configuration yet, and when downgraded it to 11.4 the issue disappeared. and when I upgraded another device with same platform (BIG-IP 2000s) I faced the same, but at 3600 it didn't sow up.

 

also I've question what the difference between CPU Usage & CPU Utilization.

    I noticed the same thing, but on HF1. However, my team decided to roll back before they opened up a case with F5. I thought with HF3 it would resolved.

     

    There is no difference in terms of F5 reporting on CPU Usage and CPU Utilization that I can tell.

    We still see the same Issue (in our Case on a Viprion using 2100 blades) with Version 11.5.1 HF3 (and a HF4-Eng).

     

    When analyzing the QKview, the CPU Peaks are not visible in the 'CPU Usage on Blade per Core' RRD graph.

      does "top" show the guilty process, or is TMM causing the spikes?
