Hello Leonardo,

it looks like it is caused by traffic volume:

CPU utilization for five seconds: 99%/99%; one minute: 99%; five minutes: 99%

the second 99% after / is the cpu usage from interrupts

How much traffic is going on each VIP ?

depending on the vip model and configured features 100,000 or less pps can be enough to achieve this cpu usage

use load-interval 30 on interfaces and check link usages and be focused on pps input and output

Hope to help

Giuseppe

Hello Joseph,

I wish I could have a document like this years ago when working with C7507.
