When I'm running Celery with Upstart, after a while, the child processes or the main processes die without any trace.
The Upstart script I'm using (/etc/init/celery):
description "celery"
start on runlevel [2345]
stop on runlevel [!2345]
kill timeout 20
# console log
setuid ***
setgid ***
script
chdir /opt/***/project/
exec /opt/***/virtualenvs/***/bin/python manage.py celery worker --settings=settings.staging -B -c 4 -l DEBUG
end script
respawn
When running exectly the same command without upstart (manually running the exec part), everything works …
