...cting the data for 8 hours, I have seen the cached routes count remain fairly constant, but the number of cached route objects increase from about 220,000 objects to 410,000 objects. The cached routes count remains between 4,000 and 8,000 routes. I posted a pretty graph at http://www.pier-pro.com/ip_dst_cache_leak.png (the blue line is the value of ip_dst_cache, the green value represents the count of cached routes). Once the ip_dst_cache value reaches the value of /proc/sys/net/ipv4/route/max_size then the network fails and the kernel complains about 'dst cache overflow' whenever a packet arrives....
