You guessed right... I did enable IP_ROUTE_MULTIPATH_CACHED, I have now disabled it and equal multi path routing in general (CONFIG_IP_ROUTE_MULTIPATH). As it is a production server, I'll need to schedule a reboot. The server has now been running a 2.4.26 kernel for 16 hours without any kernel panics. And the ip_dst_cache can grow and shink. cat /proc/slabinfo | grep ip_dst_cache ip_dst_cache 15300 56145 256 1022 3743 1 Hilsen Jesper Brouer -- ------------------------------------------------------------------- Cand. scient datalog Dept. of Computer Science, University of Copenhagen ------------------------------------------------------------------- - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
