[rabbitmq-discuss] Maximum Simultaneous Connections

There's no hard coded maximum in RabbitMQ. Typically you will need to 
raise the ulimit or you'll run out of file descriptors. Once you've done 
that, I don't see 10k connections as a huge deal - you'll need a 
reasonable amount of RAM but it should be very doable.

Cheers, Simon
