Sun's app server is so awesome, it only takes 200MB+ just to start with absolutely no applications loaded. Then there's the useless and memory sucking watchdog. Then on Solaris 10 you'll have another thingo service sucking up a couple hundred MB after a few hours. 4GB servers aren't recommended, they're required.
