This is because there is no guarantee that queued tasks in failed dagruns will or will not eventually run and queued tasks that will never run will consume slots and can stall a DAG. Once we can guarantee that all queued tasks in failed dagruns will never run (e.g. make sure that all running/newly queued TIs have running dagruns), then we can include QUEUED tasks here, with the constraint that they are in running dagruns." > Reporter: Alex Guziel > Priority: Minor > -- This message was sent by Atlassian JIRA (v7.6.3#76005)
