Hi,
Has anybody experience with a CSS11503 that has a SAM module having a 99-100% utilization. Can this affect the services if both the accelerator module cpu peak to 99%.
Kindly see below logs:

sounds like there is way too much traffic going through this CSS.
You will start seeing drops and have other issues with CPU at this level.

Hi all,
As per checking on the CSS if it was being attacked by DOS. It was indeed being attacked and that was the cause of the High Utilization.
Thanks,
Bryan
