I have 4 hosts connected with 4 queues to the RabbitMQ service. I have 
multiple processes making calls to each host using the queues, but what 
happens is that messages overlap giving me errors of execution. What should 
I do to prevent the processes do not overlap messages with the MQ using 

host1 <--queue1 -|
host2 <--queue2 -|--> MQ
host3 <--queue3 -|
host4 <--queue4 -|

Error because messages are overlapping.
  File "/usr/local/lib/python2.7/dist-packages/amqp/connection.py", line 
526, in _close
    (class_id, method_id), ConnectionError)
UnexpectedFrame: Basic.publish: (505) UNEXPECTED_FRAME - expected content 
header for class 60, got non content header frame instead
