i ran into this problem a while ago, and i did the following:
echo 8192 > /proc/sys/net/ipv4/neigh/default/gc_thresh1
echo 8192 > /proc/sys/net/ipv4/neigh/default/gc_thresh2
echo 8192 > /proc/sys/net/ipv4/neigh/default/gc_thresh3
and all my problems were solved

Hi,
I regularly have errors (kernel: dst cache overflow) and crash of a
firewall under Linux 2.6.17 and the route patch from Julian Anastasov.
With rtstat I see that the route cache size increases regularly without
never decreasing.
I have this parameters:
fw:/proc/sys/net/ipv4/route# grep . *
error_burst:1250
error_cost:250
gc_elasticity:15
gc_interval:60
gc_min_interval:0
gc_min_interval_ms:500
gc_thresh:4096
gc_timeout:300
max_delay:10
max_size:65536
min_adv_mss:256
min_delay:2
min_pmtu:552
mtu_expires:600
redirect_load:5
redirect_number:9
redirect_silence:5120
secret_interval:600
I can increase the maximum size of the cache, but that will do nothing
but delay the crash.
Hi,
I think that my problem comes from the route cache and not ARP cache:

- http://mailman.ds9a.nl/pipermail/lartc/2007q1/020067.html
I read several thread of discusion on this problem, but I did not find a
solution.
Regards.
