mhc controller seems weirdly busy, always trying to find targets to reconcile, while there is nothing to reconcile. All machines are up and mcp properly applied.

    4.12.36

  Unsure, we're seeing that on 300+ nodes cluster on openstack. Here 1 mhc selects 33 machines  

    1.
    2.
    3.
    

    Unsure, I would have expected 1 check for each mhc every 5 minute. For this particular mhc we're seeing one log:
machinehealthcheck_controller.go:192] Reconciling openshift-machine-api/xxxx-cdbfg-worker-b2-xxxx: finding targets
every 2 seconds.

Overall we're seeing 280 "finding targets" per minute, and 3000 "machinehealthcheck_controller.go:469] Reconciling openshift-machine-api/xxxx/yyyy/zzzz: health checking
per minute

    reasonably less checks per minute

    I believe it could be facilitate race conditions as mentioned in OCPBUGS-33584
