AS v3 Memory Usage

[Jason Huddleston]

Ryan,
	From what I have read on memory usage in Red Hat ES the system will
use what it needs for programs and use the rest for cache. If you take the
amount of memory used (475574272) minus the amount cached (319148032) from
the /proc/meminfo file you will have the amount that the system is actually
using for programs.

For starters, please give us the output of free, because many people
read that incorrectly and think they're using a lot more memory than
they really are.

You can also cat /proc/meminfo for some memory info.
