Component Readiness has found a potential regression in the following test:

[Monitor:legacy-test-framework-invariants-pathological][sig-arch] events should not repeat pathologically

Several serial-techpreview jobs have similar symptoms:

• CAMGI shows config-operator with some weird conditions
• The test reports events like:

  event happened 25 times, something is wrong: node/ci-op-l3l3n3qk-863c8-8ftrw-worker-a-kxq6j hmsg/8a96eaa4fd - reason/ConfigDriftMonitorStopped Config Drift Monitor stopped (21:44:31Z) result=reject 
  event happened 23 times, something is wrong: node/ci-op-l3l3n3qk-863c8-8ftrw-worker-a-kxq6j hmsg/ddacfb2151 - reason/RemoveSigtermProtection Removing SIGTERM protection (21:39:14Z) result=reject

• There are also interesting errors in config-operator pod logs (in the test_details artifact query try queries for

  artifacts: artifacts/*e2e*/gather-extra/artifacts/pods/*-config-operator*.log
  regex match: ^E10
  

  ) that may or may not be related, for example:

  E1011 21:22:58.621516 1 base_controller.go:279] "Unhandled Error" err="ConfigOperatorController reconciliation failed: configs.operator.openshift.io \"cluster\" not found"
  E1011 21:31:20.760529 1 leaderelection.go:429] Failed to update lock optimistically: Timeout: request did not complete within requested timeout - context deadline exceeded, falling back to slow path
  E1011 21:32:20.761894 1 leaderelection.go:436] error retrieving resource lock openshift-config-operator/config-operator-lock: the server was unable to return a response in the time allotted, but may still be processing the request (get leases.coordination.k8s.io config-operator-lock)
  

The regression linked below is one example of the problem which is triaged across multiple platforms.
