How is it a waste? By complining something things get moved into memory, simply by not clearing that memory after the task is done is hardly a waste! The memory isnt active, so it can be used by other programs if its needed, but should the data in it be needed again its still there and saves a whole heap of time accessing disks.. Its a win-win situation here... The memory is 'free' to be used but cached at the same time! > So, FreeBSD is best used for a server system, where you have more RAM than > you use for all normal activity, and to prevent some seldom used tasks to > hog up memory, you should reboot often.

You can... Try reading some man pages... But the point is the program is NOT hogging up anything!! And free memory is wasted memory! Its a good thing when you have very little free memory and lots of cached and inactive, you DONT want free memory!
