"free" is pretty much irrelevant for detecting kernel mem leaks because it's hard to tell if the mem is just used for caching. Anyway, post some numbers. If you see the slab growing it would be nice to know which one. Try slabtop. What exactly do you mean by OOM? Does the kernel die or start to kill processes? Johannes
