You do know that file cache is counted in the amount of free memory on
a linux system. So any linux box that is on for long enough will show
only a few MB free? Unless you are seeing swap being used there should
be no problem with this and you probably do not need any more memory.

My home computer has 4GB of memory and from the free command I have
33MB free but 3.15GB of my memory is file cache.  I rebooted yesterday
so I would expect the 33MB to go down some more.

# free
             total       used       free     shared    buffers     cached
Mem:       4048432    4015412      33020          0     177512    2942980

Swap:      7823632        696    7822936
