If you realised that high Control plan CPU due to ASM Obfuscation process , that's not an issue or can cause a negative impact :

Hi Mohamed,

thank you, I got 30 Minutes ago the reply from F5 support with the same Info.

The Background Task of Obfuscation startet every day at 9:38 am, now I resceduled it to 10 pm

So it was apparently not realy a problem, but I was very concerned

Thank you guys for your help

I expected that too from the graphs , it follows the same trend everyday , which me some tasks or processes runing in the background.
So it was the ASM Obfuscator

Great to find the needed clarifications. 🙂
