Dst cache overflow with FC2 and FC3

[Deron Meranda]

Hmm.  I now think that your dst cache overflows are related to routing
tables and not connection tracking.

In particular, what's,
  # cat /proc/sys/net/ipv4/route/max_size
  # grep  dst_cache  /proc/slabinfo

Also, are you using IPv6 as well as IPv4?
What's your routing situation, do you have lots of dynamic routes, or other
complex setups?  What about dynamic interfaces (e.g., PPP) that are
always being brought up and down?

Also try,

  # ip route list table all

And, have you since updated your kernel to 2.6.9-1.724_FC3, and are you
still experiencing the overflow?
