You should be able to fire up another instance of memcached to utilize as much memory as needed beyond the 2G barrier.
Is there a reason why there is a 2G barrier? Does this have any affect on performance going larger/smaller or running more instances? Would it be more effective to run 4 512mb instances rather than 2 2G instances?
