When creating KataConfig resource, the monitor PODs goes through multiple restarts before stablizing
Initial state
$ oc get pods -n openshift-sandboxed-containers-operator NAME READY STATUS RESTARTS AGE controller-manager-849cdfd7b4-74wfn 1/1 Running 0 10m openshift-sandboxed-containers-monitor-2f9zh 0/1 CreateContainerError 0 3m10s openshift-sandboxed-containers-monitor-2xg9m 0/1 CreateContainerError 0 3m10s openshift-sandboxed-containers-monitor-5jzb7 0/1 CreateContainerError 0 3m10s
Final state
$ oc get pods -n openshift-sandboxed-containers-operator NAME READY STATUS RESTARTS AGE controller-manager-849cdfd7b4-74wfn 1/1 Running 0 35m openshift-sandboxed-containers-monitor-2f9zh 1/1 Running 12 28m openshift-sandboxed-containers-monitor-2xg9m 1/1 Running 43 28m openshift-sandboxed-containers-monitor-5jzb7 1/1 Running 28 28m
