kernel: dst cache overflow

[André Cruz]

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 at 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
