      Description of problem:

      Hi Team ,                                                                                                                      The The customer is experiencing sudden spikes in CPU usage on Master1 node.
      
       ARO SRE team observed the increased API server load may be from 4,791,737 failing requests/day (~55 per second) from cronjobs/job-controller attempting to create pods in the "et-conference-dev" namespace which fails due to exceeded quota: ("pods "et-abs-cron-job-29243370-z9275" is forbidden: exceeded quota: et-conference-dev-rq, requested: limits.cpu=750m, used: limits.cpu=3850m, limited: limits.cpu=4")
       
       Also, observed load is coming from datadog running on the master nodes.
       
      The ARO SRE team observed that the registry-server in redhat-operators is highly active, and the logs are not providing useful insights. 
      Additionally, the apiserver and openshift-marketplace are consuming significant CPU resources.
      Those CPU Spikes seems to be caused by redhat-operators on a similar known issues:
      https://issues.redhat.com/browse/OCPBUGS-48696 and https://issues.redhat.com/browse/OCPBUGS-58070

      Thanks.
