I'm using FreeBSD 8.1-201008 amd64 snapshot.
When I watch log messages I see "kernel: arpresolve: can't allocate
llinfo for 10.0.16.251" messages repeating once per 2 minutes.
When I saw this log, default router changes unexpectedly. Normally
default router should be 193.X.Y.Z, but after this log default router
shown as 10.0.16.251. And routing really changes. I watch the changes
on routing table via "route -n monitor" command. I couldnt see
anything about default route changes.
I tried with both net.inet net.inet.flowtable.enable=0 and
net.inet.flowtable.enable=1. Nothing changes.
I think, arp table overflows and overwrites the routing table.
I captured the packges while this problem occurs. the tcpdump file:
tcpdump -w /home/flowdata_10_0_16_251 -ni bce0.116 host 10.0.16.251
system has 2x 4core Xeon, 32GB ram, about 5000 clients and 152 if_vlan
interfaces, 5 real NICs.
