I configures in my Ubuntu and Apache server a Django project in which I use celery to manage and handle backgound jobs/tasks.
The problem that I see is that when there is a queue of tasks and is managing 3, if the 4th, 5th… do not start executing within an hour they duplicate.

Here is what i have…
Supervisor conf

[program:project_app]
command=/path/celery -A haus worker --loglevel=INFO -c 3
directory=/path/
user=www-data
autostart=true
autorestart=true
stdout_logfile=/path/celeryd.log
redirect_stderr=true

celery.py
from future import absolute_import
import os
from celery import Celery
from django.conf import settings

os.environ.setdefault(‘DJANGO_SETTINGS_MODULE’, ‘project.settings’)

app = Celery(‘project’)

app.config_from_object(‘django.conf:settings’)
app.autodiscover_tasks(lambda: settings.INSTALLED_APPS)

init.py

from __future__ import absolute_import, unicode_literals
from .celery import app as celery_app
__all__ = ('celery_app',)

settings.py

...
BROKER_URL = 'redis://localhost:6379'
CELERY_RESULT_BACKEND = 'redis://localhost:6379'
CELERY_ACCEPT_CONTENT = ['application/json']
CELERY_TASK_SERIALIZER = 'json'
CELERY_RESULT_SERIALIZER = 'json'
CELERY_TIMEZONE = 'America/Mexico_City'
...

The way i execute is:

@shared_task()
def do_some(args):
# code

do_some.delay(args)

Here you can see how the first 2 are executed once and the last 2 repeated or reexecuted
