>                 Key: AIRFLOW-1434
>                 URL: https://issues.apache.org/jira/browse/AIRFLOW-1434
>             Project: Apache Airflow
>          Issue Type: Bug
>    Affects Versions: Airflow 1.8
>         Environment: We're running airflow on centOS with LocalExecutors on top of Postgres
>            Reporter: Patrick Rice
>
> We have a sensor that we've created used within multiple DAGs. Unfortunately, the sensor
task was running while a dag was shutdown. Since that time period, we have been unable to
get the scheduler to create a new task_instace for the sensor, and the sensor immediately
succeeds on every DagRun, whether manually triggered or scheduled.
> It's also worth noting that the sensors reside in a sub-dag, and that there are 2 separate
subdags within the same parent dag that are affected. Similar patterns on other dags function
as expected.
