def form_valid(self, form): schedule = CrontabSchedule.objects.get_or_create(minute='*/1') task = PeriodTask.objects.create(name='feedback_email', task='proj.tools.tasks import send_feedback_email_task', crontab=schedule) return HttpResponseRedirect(self.get_success_url())

The celery beat log shows the current schedule as below

<ModelEntry: taskname proj.tools.task.send_feedback_email_task(*[], **{}) <crontab: */1 * * * * (m/h/d/dM/MY)>> Beat: waking up in 5.00 seconds

Looks like it is not sending task when it is due.

isn't there any solution to this problem yet? I've tried ClockedTime and CronSchedule but nothing works.

I have the same issue, where all I see is Beat: waking up in 5.00 seconds repeating itself indefinetly (debug logging mode)

I am running the celery-beat, celery and django all in a docker compose environment. The celery worker is picking up the tasks from my django app properly but the celery-beat isn't sending any tasks, it is just repeating the wake up sequence mentioned above.

I did have the same issues with periodictask, but I solved by clean up the start_time field in django_celery_beat_periodictask model, this issued must be related to TZ settings, the timezone setting caused it. Take a look at your periodictask in sql and clean up this field, works for me. PS. I just tried with periodictask, and it's fine, not sure if works for the other task type.

I was having the same issue. Updating celery beat to 2.2.1 solved this issue.

set to null

set to null

Okay in my case its already set to NULL but main problem i am facing is that periodic tasks stop working midway. Happened couple of times. Do you have any workaround for this?

having the same issue , tasks were present in periodic task table but were not sent to celery workers also i had disabled the celery cleanup task , can it be a reason for tasks not being sent to workers ?
