that could be the issue. definatly something to look at.
i would lean more towards using the top command to find out what is causing the issue.
With ASM - i would further be concerned about spinning disks vs. SSD which will show up as a 'wa' in the top stastics.PhatANhappy mentioned about too small resources and that this is control plane utlization not data plane and the ''top'' will review if it is the bug or another process. About the ''wa'' that is something I would also renember from this discussion.
About the Analysis plane this in most cases is the ASM/AWAF policy builder learning, so also better also switch it off The BIG-IP ASM device shows high CPU usage in Analysis plane (f5.com) but this is could be still related to not enough resources for LTM + AWAF.
