So we figured out what the problem was: It had nothing to do with a big DAG, but with a faulty airflow deployment. When we took the deployment down, it kept a lock in the `serialized_dag` table in our postgres database. When the correct deployment went up, it was unable to make changes to the values in that table. Hence, every time the scheduler tried to validate the tasks, it could not find them in the database and marked them as removed. Simply restarting the database fixed our problem. -- This is an automated message from the Apache Git Service.
