Yeah, over 81% of your memory is consumed by slab and that doesn't shrink
over the duration of the log you posted. It would be interesting to see
if there was a leak somewhere: try looking at slabtop and determining if
you have a cache using an egregious amount of memory; if there aren't any
clear winners, then we'll still see what is hogging most of your memory
and see how it compares to 3.4.2. You can also check if there is a leak
using kmemleak, but this requires a reboot (see
Documentation/kmemleak.txt).
