@lukas the message comes from supervisor + rabbitmq . Related : https://github.com/docker-library/rabbitmq/issues/453 . I think rabbitmq is creating processes that it doesn't clean up after. RabbitMQ expects the init to clean things up. In our case, this is supervisor. This is just informational, so I think it's safe to ignore.
