**Possible fix** I was having the same problem after upgrading from Airflow `v1.10.15` to `v2.2.5` and was seeing the error in long-running DAGs having a fairly high number of tasks. Apparently, the `dagrun_timeout` in `airflow.models.DAG` was not respected in earlier Airflow versions so I noticed that the DAGs I was trying to migrate to the new Airflow instance were running for much longer than the specified `dagrun_timeout`. The solution for me was to simply increase the `dagrun_timeout` (e.g. to `dagrun_timeout=datetime.timedelta(minutes=120)`). Note that this variable is effective only for scheduled tasks (in other words with DAGs with a specified `schedule_interval`). -- This is an automated message from the Apache Git Service.
