I followed the doc (http://docs.celeryproject.org/en/latest/userguide/periodic-tasks.html) and write a Periodic Task , add CELERYBEAT_SCHEDULE in django settings.py, and run it in supervisor: celery -A proj worker -B

But now I do not want the Periodic Task anymore. I delete the schedule in settings.py, and change command in superviosor to: celery -A proj worker without celery beat, and reload it.

but once I run celery, there are still Periodic Tasks running.

I event delete all data in djcelery and celery beat pid file. But it does not help.

How can I remove the Periodic Task ?
