      First failure: https://prow.ci.openshift.org/view/gs/test-platform-results/logs/periodic-ci-openshift-release-master-ci-4.21-e2e-aws-upgrade-ovn-single-node/1973871172349071360

      Upgrade to https://amd64.ocp.releases.ci.openshift.org/releasestream/4.21.0-0.nightly/release/4.21.0-0.nightly-2025-10-02-215712 from https://amd64.ocp.releases.ci.openshift.org/releasestream/4.21.0-0.nightly/release/4.21.0-0.nightly-2025-10-02-002727

      : [Monitor:legacy-test-framework-invariants-pathological][sig-arch] events should not repeat pathologically for ns/openshift-kube-apiserver-operator
      
      {  1 events happened too frequently
      event happened 25 times, something is wrong: namespace/openshift-kube-apiserver-operator deployment/kube-apiserver-operator hmsg/6de5680bef - reason/OperatorVersionChanged clusteroperator/kube-apiserver version "operator" changed from "4.21.0-0.nightly-2025-10-02-002727" to "4.21.0-0.nightly-2025-10-02-215712" (23:02:22Z) result=reject }
      

      We suspect https://github.com/openshift/origin/pull/30272 which modified the pathological events test and first landed in 4.21.0-0.nightly-2025-10-02-215712

      We are suspecting a change in some kind of allowlist that makes these surface as failures, because these high event counts can be observed in older jobs, but they dot not trip the failure.
