In the past, I've used something like this:

netstat -an | grep FIN_WAIT_1 |
perl -pe 's/.*\s((?:\d+\.){3}\d+)\.(\d+)\s*((?:\d+\.){3}\d+)\.(\d+).*/tcpdrop $1 $2 $3 $4/' |
sh -x

This relies on tcpdrop, included as /usr/sbin/tcpdrop on FreeBSD 6.x; you 
may need to install it from a port on FreeBSD 4.x.
