I am also observing the same issue. I can add that it is not limited to `max_active_runs = 1`. We tried to increase `max_active_runs` in the hope to speed up things, but the same deadlock for other DAGs was still present. We have Airflow 2.1.3 deployed on k8s using the unofficial helm chart at https://github.com/airflow-helm/charts. We mostly have default config settings. Changes related to the scheduler are these: ``` AIRFLOW__SCHEDULER__PARSING_PROCESSES: "4" AIRFLOW__SCHEDULER__PROCESSOR_POLL_INTERVAL: "3" AIRFLOW__SCHEDULER__MIN_FILE_PROCESS_INTERVAL: "60" ``` -- This is an automated message from the Apache Git Service.
