Hi Jeff, "java.net.BindException: Address already in use" indicates there is another process using this ip/port. You'll need to change it to a unique value. Dan

Maybe RackSpace's default rules are somehow blocking access, even though there are no explicit firewall rules blocking 4000-4099. I don't know. I had this same cluster configuration up and running on my MacBook Pro without any issues. But now I am at a loss. Can anyone point me in a direction to investigate further? Thank you!
