You misunderstand the way that the Linux kernel manages memory.  It will
not reclaim memory until it runs out of space.  This is because if you
need something that was already in memory, then it costs nothing to
simply refer back to that which is already in memory.  If the memory
were automatically reclaimed after some idle period of time and you
then referenced the same information, it would need to be returned to
memeory, which is a waste of resources.  There is nothing wrong with
your system.  You know that it fills up the RAM completely if you start
using swap space.  That is when you might want to worry.
