Oddly enough, over the same period it appears that
MemFree + Active + Inactive + Slab + PageTables
is basically (+/- half a meg) constant and equal to "MemTotal - 48.5MB".
It would seem that active/inactive track memory that isn't visible in Buffers+Cached+AnonPages+Mapped. Anyone have any suggestions what it might be?
Thanks,
