Celery Periodic task getting executed multiple times

sandhuharjodh commented 3 years ago

I have a celery task that is scheduled to run at a specific time of the day. The problem is this task is getting executed multiple times, so I am receiving the same email at least 2 to 3 times.

Celery Version: 4.4.1
Celery-Beat Version: 2.0.0

Detailed information

@periodic_task(run_every=crontab(hour=7, minute=10))
def send_reminder_email_at_7():
    obj = Service()
    obj.send_email()
    return

On server, I have setup the project using gunicorn and the supervisor Following is the configuration of celery and celery beat

[program:proj_worker]
command=/home/ubuntu/venv/bin/celery -A baseproj worker -l debug
directory=/home/ubuntu/proj/
user=ubuntu
numprocs=1
stdout_logfile=/home/ubuntu/logs/celerylogs/proj_worker.log
stderr_logfile=/home/ubuntu/logs/celerylogs/proj_worker_err.log
autostart=true
autorestart=true
startsecs=10
stopwaitsecs = 600
killasgroup=true
priority=998
