After Dennis' indication that the problem was FreeBSD-stable and rather strong suggestion that I need to be running 2.1.0, I have reinstalled this system running stock FreeBSD-2.1.0. The problem still exists and can be directly related to activity over the 56K connection. A much busier system of same kernel vintage without the ET drivers hovers at around '75 mbufs in use' after several days of uptime. The system will reach it's max of 4096K after about 48 hours of uptime and eventually reboot. I'm at a loss for how to track this down and would heartily welcome more productive suggestions.
