That's banging away pretty hard with creation attempts that keep getting 409ed, presumably because an earlier creation attempt succeeded. If the controller needs very quick latency in re-creation, perhaps an informing watch? If the controller can handle some re-creation latency, perhaps a quieter poll?
Version-Release number of selected component (if applicable):
4.14.2. I haven't checked other releases.
How reproducible:
Likely 100%. I saw similar behavior in an unrelated dump, and confirmed the busy 409s in the first CI run I checked.
Steps to Reproduce:
1. Dump a hosted cluster.
2. Inspect its audit logs for hosted-cluster-config-operator-manager create activity.
Actual results:
$ curl -s https://gcsweb-ci.apps.ci.l2s4.p1.openshiftapps.com/gcs/origin-ci-test/logs/periodic-ci-openshift-hypershift-release-4.14-periodics-e2e-aws-ovn-conformance/1722648207965556736/artifacts/e2e-aws-ovn-conformance/dump/artifacts/namespaces/clusters-e8d2a8003773eacb6a8b/core/pods/logs/kube-apiserver-5f47c7b667-42h2f-audit-logs.log | grep -v '/var/log/kube-apiserver/audit.log. has' | jq -r 'select(.userAgent == "hosted-cluster-config-operator-manager" and .verb == "create") | .verb + " " + (.responseStatus.code | tostring)' | sort | uniq -c
130 create 409
Expected results:
Zero or rare 409 creation request from this user-agent.
Additional info:
The user agent seems to be defined here, so likely the fix will involve changes to that manager.
