Doc Text:
Cause: intermittent availability issues with the apiserver could lead to intermittent issues with the openshift controller manager operator retrieving deployments it manages Consequence: a failure to retrieve a deployment at the wrong moment resulted in the openshift controller manager operator making a nil reference that results in a panic in the operator Fix: nil reference checks are now in place to handle this error condition, report it, but also retry again per expected controller operations. Result: openshift controller manager operator properly handles intermittent issues retrieving deployments from the api server.
