    • 3/12: Root cause identified as increase in kubelet CPU utilization (OCPBUGS-30652). Will keep this Jira open until that issue is fixed.

      Description of problem:

      Version-Release number of selected component (if applicable):

          at least as far back as OCP 4.15.0-rc.5 and newer

      How reproducible:

          Always

      Steps to Reproduce:

          1. Deploy SNO spoke with Telco DU profile applied
    2. Run cpu_util and review results
    3.

      Actual results:

          increase cpu utilization 20% - 56% depending on management pod, as noted during steady workload 12h test in cpu_util  run

      Expected results:

          CPU utilization metrics should be close to or lower than previous release z-streams
