CirrusAbnormal 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.

rolfWe 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.
- shaggydoes "top" show the guilty process, or is TMM causing the spikes?
