Hi Steven. Which version of RabbitMQ are you using? - that sounds like a 
way 1.x might crash. Is there anything in the logs?

Have a look at the management plugin:

and at rabbitmqctl:

Rabbit shouldn't require anything too ridiculous in terms of power. 
Having said that, Windows is a bit limiting as Erlang only exists in 32 
bit form for that platform, so you can't go to more than ~2GB memory used.
