At first, I would say sit is leaking percpu memory Load sit module, then : while : do ip netns add foo ip netns del foo done Will eat all memory eventually. ipip6_tunnel_init() and ipip6_fb_tunnel_init() are _both_ called for the sit0 device, this looks very wrong. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
