Could not connect, 0 attempts left #246

Hi,

I am periodically seeing the following errors in the logs:

[2018-06-15 15:01:32,363: ERROR/ForkPoolWorker-5] Connection to 10.0.0.6:5672 failed: timeout [2018-06-15 15:01:32,363: WARNING/ForkPoolWorker-5] Could not connect, 0 attempts left

I'm using celery 4.1.0 with RabbitMQ connection (amqp=2.2.2). What happens to the celery process in these situations (is it killed and the task is lost, or is it able to recover)? What could be causing this situation?

Thanks.
