Comment 3 Joao Fula 2022-04-05 06:41:50 UTC
Verified on 4.9.0-0.nightly-2022-04-04-160205.

Steps to reproduce:
1.  Create a new namespace called dc-test
2.  Get the uuid from the yaml definition of the newly created namespace.
3.  Create new DeploymentConfig - you have to pass your uuid there in the ownerReference:

apiVersion: apps.openshift.io/v1
kind: DeploymentConfig
  name: example-aaa
  namespace: dc-test
   - apiVersion: v1
     kind: namespace
     name: dc-test
     uid: <PUT YOUR UUID>
    app: httpd
  replicas: 3
        app: httpd
        - name: httpd
          image: >-
            - containerPort: 8080

4.   Stop the openshift-api with

oc patch openshiftapiservers.operator.openshift.io cluster --type merge --patch '{"spec": {"managementState": "Removed"}}'

5.  Delete the dc-test namespace.
6.  Start back the API so that you can read the logs (not sure if it's required)

oc patch openshiftapiservers.operator.openshift.io cluster --type merge --patch '{"spec": {"managementState": "Managed"}}'

7. Restart IO
8. Download archive and navigate to config/pod/openshift-kube-controller-manager/logs/{pod-name}/errors.log

Check if logs contain "syncing garbage collector with updated resources from discovery (attempt 1):"
