Alexis,

I believe we have a fault in the task function that is run by celery
(i.e. in our code) with the effect that a *new* rabbitmq connection is
opened upon every invocation while the already utilised ones cannot be
"garbage collected" for some reason.

We should never have that many open connections. Looking into this..

Best regards/Mit freundlichen Grüßen
