Take a look at

If you can configure your system to preserve a crash dump and extract
from it a backtrace which you then use send-pr(1) to send in, you
should find a developer willing to help you.

See also Michael Lucas' Big Scary Daemon articles:

However, crash bugs like this do not appear spontaneously: something
in your environment changed to cause the problem.  A prime suspect
would be hardware failure -- if you have the resources to do so, try
swapping out components to see if you can isolate the problem.  Don't
forget to swap out the simplest parts, like network cables.  Another
prime suspect would be recent changes made to the configuration of
your system or the network it is attached to.  Given the nature of the
panic, changes to the way routing is done would be a good place to
start investigating.  (Nb. if it turns out to be a change that someone
else made on a machine elsewhere on your network, then reporting the
problem to the FreeBSD developers would become imperative: remote
crash bugs are very bad news indeed)

This topic is best dealt with on the freebsd-stable at ... list -- please
post any follow up there. (Reply-to: set appropriately).
