      [sig-arch] events should not repeat pathologically for ns/openshift-cluster-csi-drivers

      Probability of significant regression: 99.45%

      In all three failures, the event is about deletion of vmware-vsphere-csi-driver-node-xxxx pods. Here is an example job

       

      Error message from the test:

      {  1 events happened too frequently
      
      event happened 22 times, something is wrong: namespace/openshift-cluster-csi-drivers daemonset/vmware-vsphere-csi-driver-node hmsg/6fee4a4ed8 - reason/SuccessfulDelete (combined from similar events): Deleted pod: vmware-vsphere-csi-driver-node-prkn5 (04:29:41Z) result=reject } 

       

      Event filter shows that this affects pod vmware-vsphere-csi-driver-node-prkn5 22 times:

      04:29:41 (x22)openshift-cluster-csi-driversdaemonset-controllervmware-vsphere-csi-driver-nodeSuccessfulDelete(combined from similar events): Deleted pod: vmware-vsphere-csi-driver-node-prkn5 

       

      It is worth mentioning though that the audit log does not seem to indicate the deletion is called that many times for vmware-vsphere-csi-driver-node-prkn5.

      So feel free to reassign if you deem this belonging to another component.
