FYI, today it looks like this: bash-2.05a# cat /proc/net/rt_cache | wc -l; grep ip_dst /proc/slabinfo 26 ip_dst_cache 820 1065 256 15 1 So the dst cache seems to have grown by 151 in 16 hours... I'll continue monitoring and providing updates. -- Russell King Linux kernel 2.6 ARM Linux - http://www.arm.linux.org.uk/ maintainer of: 2.6 PCMCIA - http://pcmcia.arm.linux.org.uk/ 2.6 Serial core - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
