Yup, edit your rabbitmq.config file. You want to add a stanza including
{msg_store_file_size_limit, 16777216}. 16777216 is the default and is
16MB. You can reduce this as much as you'd like but if you make it too
small then you'll find performance starts to drop off. The minimum
rabbitmq.config file with this in is:

[{rabbit, [{msg_store_file_size_limit, 16777216}]}].

Note the trailing . is essential. According to
http://www.rabbitmq.com/install.html#configfile, under Windows, the
config file might be found in %APPDATA%\RabbitMQ\rabbitmq.config

Best wishes,

Matthew
