You don't provide quite enough information to be sure, but it sounds
like you've hit on a common misconception.  It is _normal_ to "use all
available memory" on Linux. Looking at "top" output for example,
you'll find that much of the used memory is being "consumed" in
buffers and cache.  That memory is immediately releaseable should an
application require it.  In Linux, just try to remember the adage:
"free memory is wasted memory".

On the other hand, I am not intimately familiar with your specific
situation, so I may have misinterpretted.  If that's the case: "never
mind". ;-)
