Description of problem:

customer is encountering two interconnected problems:

1. Managed cluster add-ons (managed-serviceaccount, work-manager, and cluster-proxy) are being deleted and recreated in a loop across almost all managed clusters.
2. Certain managed clusters are missing necessary proxy secrets (cluster-proxy-hub-kubeconfig and cluster-proxy-open-cluster-management.io-proxy-agent-signer-client-cert), which are related to the first issue.

After adding the below recommended toleration to the placement resource stabilized the situation:
~~~
tolerations:

• key: cluster.open-cluster-management.io/unreachable
  operator: Exists
• key: cluster.open-cluster-management.io/unavailable
  operator: Exists

~~~ 
Need to identify the root cause why ACM controllers continue to reconcile the addons when the managed cluster condition remains stable.
