This patch adds a prefetch size of 1 to the background jobs worker,
so that it fetches 1 message at a time. Without this change,
the RabbitMQ connection timeout when too many messages for slow tasks
are fetched at the same time.
To test:
0. Apply patch
1. Run background worker
2. Rapidly enqueue multiple jobs that in total will take longer
than 30 minutes to process
Bug 32481: Use correct prefetch syntax for RabbitMQ
According to https://www.rabbitmq.com/stomp.html the header to
use for managing the prefetch is "prefetch-count".
You can verify the number of delivered and unacknowledged messages
on a channel on a connection by running "rabbitmqctl list_channels"
on the RabbitMQ host. This will tell you how many messages have been
delivered and are awaiting acknowledgement
