Sorry for coming back to this so late. I am using a GNU/Linux but with a
kernal that has a 16k page size. I think that might be the problem?

I don't understand C at all but I looked at the sysdep.c as weird math.
What stands out is line 3741:

	  pmem = 4.0 * 100 * rss / procfs_get_total_memory ();

The 4.0 is what makes me suspicious but it is just a hunch without any
understanding.

Thanks,
