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). -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
