It looks like there's a bit going on here: you're using dummynet and
netgraph, too?  If this setup is unstable, or otherwise problematic,
I'd suggest asking on the freebsd-net mailing list.  I don't have much
experience with some of these utilities, and I've haven't been running
FreeBSD 7-* for a long time, so I've lost track of what problems have
been fixed and back-ported.  You may also want to look at your network
and polling MIB and debugging variables, to see if they indicate any
problems.
