First off, let’s make sure it’s actually used, not just in buffers/cache. Run this, and give us the output:

free -m

Here’s an example output:

            total       used       free     shared    buffers     cached
Mem:          7872       7707        165          2        272        432
-/+ buffers/cache:       7002        870
Swap:         3967        310       3657

Now, it’s showing 165M free. Oh noes. Well, not really.

Let’s look at the 2nd line

-/+ buffers/cache:       7002        870

It has 870M free. Let’s add that with the other free (ignoring the Swap line, if you have one).

165+870 = 1035 (or ~1GB) free.

So, in summation, you may not actually be out of RAM. It may just be cached. For more info on caching, go to linuxatemyram.com
