We are experiencing many occurrences of replicas drifting in and out of warning state and the description reads 'The api IReplicator.BuildReplica(<ID>) on node <NODE NAME> is stuck' (see image 1 below). This often leads to nodes getting placed into a Disabling/Disabled state (as seen in image 2 below) and system services such as the FailoverManagerService and the ImageStoreService entering warning state also.
Can anybody assist as to what are the best ways of inspecting what is going on here and understanding why it is dropping into these warning states?


Thanks!
