Error Message :
N/A

Queue slots are not released after a Workflow has been canceled by the last Task inside a Workflow.

In order for this issue to occur when a Workflow (i.e. WF1) is submitted into a queue and one of the internal tasks within the workflow aborts, WF1 will remain in the queue in a status of BLOCKED.  If a second Workflow (i.e. WF2) is submitted in the same queue that workflow will remain in a status of Waiting for Predecessor.  Because the Job Queue is limited to a maximum of 1 Job execution at a time, the workflows are behaving as expected.

If the failed job within WF1 is executed again and it ends successfully, WF1 will continue and end in a status of ENDED_OK.  The job queues slot is now released and WF2 should start. Instead, WF2 remains indefinitely in a status of Waiting for Predecessor.
