A slow moving process will only get garbage collected occasionally; to 
be honest I would consider ~3MB to be within the levels of GC noise here.

You could try something like:

rabbitmqctl eval '[{pid, Pid}] = 
rabbit_amqqueue:with(rabbit_misc:r(<<"/">>, queue, <<"test">>), fun(Q) 
-> rabbit_amqqueue:info(Q, [pid]) end), garbage_collect(Pid).'

to forcibly garbage-collect the queue and see if that cuts memory use.

But I would only worry if the memory use kept growing quite a long way 
past 3MB.
