Apparently Windows has problems releasing file cache memory
even if it doesn't need it anymore which results in the RAM
allocated to file cache growing and growing up to max limit.

Yes, under Windows 98.  If you istall more than 512MB of RAM, you have to
edit the System.INI file so the cache's don't use more than that or you'll
get serious performance hits.
