Hello.
It's my understanding that Linux will attempt to use as much RAM as it
can for processes.  If necessary, it will start swapping.  This is a
performance issue, as RAM is faster.  Of course, you may also have a
memory leak, in which case one would expect to see programs crashing
and dying.

Look at http://metalab.unc.edu/pub/Linux/docs/FAQ, section 6.4,
www.kernel.org, www.linuxhq.com, and others linked off those
sites.

http://metalab.unc.edu/pub/Linux/docs/LDP/linux-kernel/
has the kernel-howto in various formats.  It tells you exactly how
linux deals with memory (chapter 3).
