On the other hand, I recall reading somewhere before that due to the
paging mechanism
Linux is also supposed to start using as much memory as you give it? Just
confused if this is something I need to worry about or not.
Yes, Linux caches as much in memory as it can, and this is a good thing.
But that memory gets released when it's needed by an active process. So,
above, you have 7148804k used, but the vast majority (6380236k), is cache.
If you use 'free', it'll show you the amount not counting buffers+cache.
In short -- situation normal, nothing to see here, move along.
