afaik `mvcc: required revision has been compacted` is a healthy message. Why does it need to be emitted as an error though? The frequency is also concerning. We agree, it should be fixed, setting the target release to 4.5. The expectation is: - This is a healthy message, so we might need to find a way to make it less frequent. - This should not be labeled as an error message. Reduced to warning in https://github.com/kubernetes/kubernetes/pull/84602 with 1.18 rebase. Verified in 4.5.0-0.nightly-2020-05-11-032504. Now OAS log shows it as Warning. $ oc logs -n openshift-apiserver apiserver-79d4f8fd98-9j5bj ...
