Looks like your server is maxed out 2 gig memory is barely enough when a full server will use close to 1 gig of memory itself. That doesn't leave anything for your operating system, etc. We run dual quad 5520's with hyper threading and 12-24 gig memory for our customer set ups. If your running 2 instances of OA I would not run them on anything less then a quad core with 8 gig memory. When running under windows check your page file and you will probably see it being maxed out when the servers have players in them
