Does this issue impact your ability to continue to work with the product
(please explain in detail what is the user impact)?

This is impacting the cluster because some pipelines are checking OCS status and crashing because the health is in HEALTH_WARN status.


Is there any workaround available to the best of your knowledge?

For this environment, cleaning the crashes solves the issue but it's happening more frequently and a more permanent solution is needed.


Can this issue reproducible?

N/A

Can this issue reproduce from the UI?

N/A


Actual results:

rook-ceph-mon crashing making deployed pipelines that check OCS status crash and delaying application deployments.

Expected results:

rook-ceph-mon not crashing.
