Interesting. Unfortunately that kernel suffers from the newer task
scheduler they added to 3.2, and I doubt much of the fixes have been
back-ported. I don't know if that affects the memory handling, but it might.

to 64GB. Immediately afterwards the new RAM was being used for page cache,
which is what we want, but that seems to have dropped off over time, and
there's currently actually like 12GB of totally unused RAM.
