--- Comment #1 from Mark Johnston <markj@FreeBSD.org> ---
It would be helpful to see the IPFW and dummynet rules in question, otherwise
it's hard to speculate about where the problem might be.

Also it'd be useful to see output from `procstat -kk 0` when the system is in
this state, it will help show what those threads are doing.
