Сельдерей в контейнере docker сначала работает некоторое время, а затем начинает отключаться по тайм-ауту

Развертывание проекта, все работает. Через неопределенное время celery перестает отвечать. Получаю ошибку gunicorn: sys.exit(1)

Пробовал запустить task.deploy() внутри контейнера django и ничего не происходит в контейнере celery. В логах нет ошибок ни в контейнере django, ни в контейнере celery.

Контейнеры докера:

django settings celery settings:

CELERY_BROKER_URL = REDIS_URL
CELERY_RESULT_BACKEND = 'db+sqlite:///results.sqlite'
CELERY_ACCEPT_CONTENT = ['json']
CELERY_TASK_SERIALIZER = 'json'
CELERY_RESULT_SERIALIZER = 'json'

celery.py в проекте django:

os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'YoungAI.settings')


app = celery.Celery('YoungAI')

# Using a string here means the worker don't have to serialize
# the configuration object to child processes.
# - namespace='CELERY' means all celery-related configuration keys
#   should have a `CELERY_` prefix.
app.config_from_object('django.conf:settings', namespace='CELERY')

# Load task modules from all registered Django app configs.
app.autodiscover_tasks()
