Re: django/celery - celery status: Error: No nodes replied within time constraint

[Hector Armando Vela Santos]

Hi I solved my problem, it was a very simple solution, but it was also a weird one:

What I did was:

  $ /etc/init.d/celerybeat restart
  $ /etc/init.d/celeryd restart
  $ service celeryd restart

I had to do this in that order, other way I'd get an ugly Error: No nodes replied within time constraint

but if I run
celery status
in the terminal, i got this response:

I can restart celery via the celeryd script provided inhttps://github.com/celery/celery/tree/3.0/extra/generic-init.d/
/etc/init.d/celeryd restart
celeryd-multi v3.0.12 (Chiastic Slide)

> Restarting node w1.one.cloudwime.com: OK
I can run
python26 manage.py celeryd -l info
and my tasks in django run fine, but if I let the daemon do its work i dont get any results, don't even errors in /var/log/celery/w1.log
I know that my task has been registered because I did this from celery import current_app def call_celery_delay(request): print current_app.tasks run.delay(request.GET['age']) return HttpResponse(content="celery task set",content_type="text/html") and I get a dictionary in wich my task appear
{'celery.chain': <@task: celery.chain>, 'celery.chunks': <@task: celery.chunks>, 'celery.chord': <@task: celery.chord>, 'tasks.add2': <@task: tasks.add2>, 'celery.chord_unlock': <@task: celery.chord_unlock>,'tareas.tasks.run': <@task: tareas.tasks.run>, 'tareas.tasks.add': <@task: tareas.tasks.add>, 'tareas.tasks.test_two_minute': <@task: tareas.tasks.test_two_minute>, 'celery.backend_cleanup': <@task: celery.backend_cleanup>, 'celery.map': <@task: celery.map>, 'celery.group': <@task: celery.group>, 'tareas.tasks.test_one_minute': <@task: tareas.tasks.test_one_minute>, 'celery.starmap': <@task: celery.starmap>}
but besides that I get nothing else, no result from my task, no error in the logs, nothing. Can anyone tell me what can be wrong? You are my only hope...
