   I just wanted to share that the [User-Community Airflow Helm Chart](https://github.com/airflow-helm/charts/tree/main/charts/airflow) now has a mitigation for this issue that will automatically restart the scheduler if no tasks are created within some threshold time.
   
   It's called the scheduler ["Task Creation Check"](https://github.com/airflow-helm/charts/blob/main/charts/airflow/docs/faq/monitoring/scheduler-liveness-probe.md), but it's not enabled by default as, the "threshold" must be longer than your shorted DAG `schedule_interval`, which we don't know unless the user tells us.
