8.0 release notes say flowtable is enabled by default on amd64/i386.
So I presume it is enabled? I can't seem to find much information
about this for FreeBSD 9.x

It's not compiled in GENERIC on 9.x because it had/has some stability
issues.  I just wanted to make sure that the problem really come out
of the arpresolve area before digging into it.

Courtland,

the arpresolve observation is very important.  Do you have flowtable
enabled in your kernel?

Has there been any progress on resolving this problem. Does anyone have a
better idea as to where it is breaking down?

I am experiencing the same problem under FreeBSD 9.1-RELEASE. I use PF
for
NAT, ALTQ, and RDR/filter rules. I'm not using PPPoE or dhclient. The
default gateway changes to an IP that is not on my network when under
heavy
network load.

The last time this happened I had a stream of arpresolve messages in the
kernel for the IP that the default route was changed to.
Mar  5 19:12:53  kernel: arpresolve: can't allocate llinfo for
50.142.201.101
The default route was changed to 50.142.201.101 after these messages.
