>             Project: Apache Airflow
>          Issue Type: Bug
>          Components: celery, subdag
>    Affects Versions: Airflow 1.7.1.2
>            Reporter: Cyril Scetbon
>            Priority: Major

> We have a main dag that dynamically creates subdags containing tasks using BashOperator.
Using CeleryExecutor we see Celery tasks been created with *STARTED* status but they are not
picked up by our worker. However, if we restart our worker, then tasks are picked up. 
> Here you can find code if you want to try to reproduce it https://www.dropbox.com/s/8u7xf8jt55v8zio/dags.zip.
> We also tested using LocalExecutor and everything worked fine.
