@dwilson Any chance you can verify on 4.10?

@jcaamano Any good way to verify this on a small scale cluster?

Comment 5 Jaime Caamaño Ruiz 2022-07-18 14:56:52 UTC
I don’t think so. This is strictly a scale bug and the problem won’t show at small sizes. Unless we are whiling to white box it and look into the logs or just limit the verification for regressions.

Verified on 4.10.23

1. installed 4.9.43 on AWS
2. scaled cluster up to 120 nodes
3. ran the node-density-ci-networkpolicy kube-burner workload for 2600 pods as described in https://bugzilla.redhat.com/show_bug.cgi?id=2089392#c2
4. upgraded to 4.10.23 which has the fix for this bz

Upgrade successful in about 1 hr 45 min.
