    Hi,

    Far as I know, there are process on odd number core having normal spikes. As you mentioned even number core, maybe this article help your analisys: https://support.f5.com/csp/article/K63120332

    As we can find lot of information about cpu spikes, including issues, better to open a case on F5 to help you to find the root cause.

     

    Best regards,
