   > I'm on Airflow `2.1.0` deployed to ECS Fargate--seeing similar issues where they are 128 slots, a small number used, but queued tasks that aren't ever run. Perhaps relatedly I also see a task in a `none` state which I'm not able to track down from the UI. Cluster resources seem fine, using less than 50% CPU and memory.
