          Bug - A problem that impairs or prevents the functions of the product. OCPBUGS-2113 [4.11] etcd and kube-apiserver pods get restarted due to failed liveness probes while deleting/re-creating pods on SNO

          • Normal - To be worked after urgent and high priorities are resolved. This term is chosen when the severity of an issue is relatively close to the level of effort to fix it. The existence of an easily implemented workaround can also lead to this priority level instead of a higher priority.
