It is possible that what you are seeing is just an inherent symptom of 
how Erlangs memory allocation and garbage collection works. Unless 
rabbit actually ends up exceeding the configured memory high watermark 
(40% of system memory, by default) for sustained periods of time I 
wouldn't worry.

If you are planning on running this test for a while, I suggest you take 
a reading of the memory values reported by 'rabbitmqctl status' near the 
beginning and end of the run, since that will help pinpoint where the 
memory is going.

Regards,

Matthias.
