Running low on memory. Or, more accurately, rabbit estimating that it 
will run out of memory if messages keep getting produced/consumed at the 
current rates.

There is no threshold as such at which paging starts, due to the 
heuristics mentioned above. There is, however, a threshold telling 
rabbit how much memory it has to play with. See 
http://www.rabbitmq.com/extensions.html#memsup. I recommend not fiddling 
with that.
