Celery worker getting crashed on Heroku

问题

I am working on a Django project which I have pushed on Heroku, for background tasking I have used Celery. Although Celery works fine locally, but on the Heroku server I have observed that celery worker is getting crashed. I have set CLOUDAMQP_URL properly in settings.py and configured worker configuration in Procfile, but still worker is getting crashed.

Procfile

web: gunicorn my_django_app.wsgi --log-file -
worker: python manage.py celery worker --loglevel=info

Settings.py

...
# Celery
BROKER_URL = os.environ.get("CLOUDAMQP_URL", "django://")
#CELERY_BROKER_URL = 'amqp://localhost'
BROKER_POOL_LIMIT = 1
BROKER_CONNECTION_MAX_RETRIES = 100
CELERY_TASK_SERIALIZER="json"
CELERY_RESULT_SERIALIZER="json"
CELERY_RESULT_BACKEND = "amqp://"
