So if I understand you correctly, you have 32 queues with six producers 
and one consumer each, and the 600k enqueued messages arise from the 
fact that consumers cannot keep up with producers?

Is it possible that a lot more messages (e.g. a few million) were 
enqueued at some point prior to settling on the 600k figure?

What else is going on in your system? The 'rabbitmqctl status' showed 
486 sockets in use, so clearly there must be more than 6*32+32=224 

Please post the output of 'rabbitmqctl report' while the system is using 
a lot of memory.
