You're likely hitting the ulimit. Edit /etc/security/limits.conf and
allow the rabbitmq user to have a much higher "nofile" setting. Rabbit
will log on start up how many sockets it's permitting, so once the
change has taken effect and you've restarted rabbit, you should find log
entries to demonstrate it's working.
