Hello,

I have recently noticed that the CPU is in full use on my 7750 SR. Most CPU is used by Services. I have not noticed any issues yet, but I'm still looking for implications of this.

Has anyone seen this before?

This will not affest your traffic even it reaches till 100% becasue control and data planes are different.
we have such issues in our routers as well and got same replies from alcatel.

Thank you so much for the response. I went as far as failing over cpu, which did not change usage.
