Hello. I have a router running FC 2 with kernel 2.6.10-1.770_FC2. Yesterday my network went down and a lot of "dst cache overflow" appeared in my console. I then increased my /proc/sys/net/ipv4/route/max_size from 8192 to 16384 and my network started to work again... The problem is that dst_cache keeps increasing: [root@saf113 root]# cat /proc/slabinfo |grep ip_dst_ca ip_dst_cache 9210 9210 256 15 1 : tunables 120 60 0 : slabdata 614 614 0 This way the problem will repeat itself... Is there a solution to this? Is this a known bug? Thanks for the help. André
