# netstat -m   
1870 mbufs in use:
        1869 mbufs allocated to data
        1 mbufs allocated to packet headers
0 calls to protocol drain routines

netstat -a shows nothing on the queues.

I assume NAT and firewall state also allocate mbufs?  how do I track
them down?

mbufs are the only data structures allocated out of mclpool?
