The workflow engine checks the cluster database to see if the status of the engine is SHUTDOWN or TIMEDOUT. If the status is STARTING or RUNNING, the workflow engine logs a warning, then waits for a heartbeat timeout to occur. Workflow Engines State displays the state of the workflow engines in the cluster:
Indicates that the engine is shutdown gracefully.
Indicates that accessing the engine is timed-out. This state depends on the specified Heartbeat Interval. See, Configure Workflow Cluster Settings.
Indicates that the engine is starting.
Indicates that the engine is active.
