Ash Berlin-Taylor commented on AIRFLOW-1131:
--------------------------------------------
[~tedmiston] I think that is a different issue to the one I commented about. It
does sound like an important feature/bug fix though so I would open a PR for it
anyway.
I think there are two different issues at work for different people in this
thread. One appears to be related to long running tasks, and the Celery config
would help with that (and I _think_) that would solve the problem the OP had.
And then there's your case which may or may not also be the problem the OP had.
