The action_manager queue on the secondary HA hub is filling up. It appears that queue's subjects already exist in Alarms_to_Primary queue and that queue is working fine. Are these duplicate queues? Would it be ok to remove the action_manager queue from the secondary?
Environment
Release: 20.4
Resolution
Let the ems probe recreate the queue.
Deactivate the ems probe
Delete the queue from the hub probe Queues Tab
Activate ems and the queue should be automatically recreated correctly
