As a RabbitMQ newbie I was thinking on this issue too: is it possible to
block publisher's send while the queue is above a certain threshold?

I am experiencing many RabbitMQ crashes because the queue size surpass the
machine memory. This is happening in many scenarios where the ratio between
#published_messages/#consumed_messages is very high (and the message size is
big). Don't know if it's very uncommon. My use case is a long text mining
pipeline where there is a lot of input data and some processes cause a
bottleneck (but with the solution exposed above the bottleneck will just
slow the publishers and every process will finish).
