Subject: Tons of free RAM. Can't make it go away.

Hey everyone!
This is pretty embarrassing, but I've never seen this before. This is
our system's current memory allocation from 'free -m':
total used free buffers cached
Mem: 72485 58473 14012 3 34020
-/+ buffers/cache: 24449 48036
So, I've got 14GB of RAM that the OS is just refusing to use for disk or
page cache. Does anyone know what might cause that?
Our uname -sir, for reference:
Linux 3.2.0-31-generic x86_64
