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).
