The classic "Where's my memory" problem.  Free memory is automatically used
for disk caches and buffers, the reported free memory is what is left over.
 When some process needs more memory than is available out of your "free"
memory, the buffers and caches reduce themselves, giving you more "free"
memory.  So, yes it is normal.  Try the "free" command.
