Description of problem:
While preparing to do IBU scale tests of 3500+ SNOs in the ACM ZTP Large Scale Environment, I have un-managed a cluster in order to create a seed image from the cluster. The cluster's namespace is still in terminating state despite having been in that state for 25 minutes now. In smaller environments the un-managing occurs in ~3 minutes. I would expect despite being in a large environment for the timeframe to do the same task to take around the same period of time.
Version-Release number of selected component (if applicable):
Hub OCP 4.15.9 Deployed OCP 4.15.0 ACM - 2.10.0-DOWNSTREAM-2024-03-14-14-53-38
How reproducible:

Additional info:
It appears that the namespace deletion is hung on an ACM OBS component: # oc describe ns vm00001 Name: vm00001 Labels: app.kubernetes.io/instance=ztp-clusters-04 cluster.open-cluster-management.io/managedCluster=vm00001 kubernetes.io/metadata.name=vm00001 name=vm00001 open-cluster-management.io/cluster-name=vm00001 pod-security.kubernetes.io/audit=restricted pod-security.kubernetes.io/audit-version=v1.24 pod-security.kubernetes.io/warn=restricted pod-security.kubernetes.io/warn-version=v1.24 Annotations: argocd.argoproj.io/sync-wave: 0 openshift.io/sa.scc.mcs: s0:c106,c90 openshift.io/sa.scc.supplemental-groups: 1011310000/10000 openshift.io/sa.scc.uid-range: 1011310000/10000 ran.openshift.io/ztp-gitops-generated: {} Status: Terminating Conditions: Type Status LastTransitionTime Reason Message ---- ------ ------------------ ------ ------- NamespaceDeletionDiscoveryFailure False Thu, 18 Apr 2024 13:27:19 +0000 ResourcesDiscovered All resources successfully discovered NamespaceDeletionGroupVersionParsingFailure False Thu, 18 Apr 2024 13:27:19 +0000 ParsedGroupVersions All legacy kube types successfully parsed NamespaceDeletionContentFailure False Thu, 18 Apr 2024 13:27:19 +0000 ContentDeleted All content successfully deleted, may be waiting on finalization NamespaceContentRemaining True Thu, 18 Apr 2024 13:27:19 +0000 SomeResourcesRemain Some resources are remaining: observabilityaddons.observability.open-cluster-management.io has 1 resource instances NamespaceFinalizersRemaining True Thu, 18 Apr 2024 13:27:19 +0000 SomeFinalizersRemain Some content in the namespace has finalizers remaining: observability.open-cluster-management.io/addon-cleanup in 1 resource instancesNo resource quota.No LimitRange resource.
