Hi, Bill,

I think it's easy to reproduce this issue with a VM (e.g., VirtialBox) installed the latest DFly release or master snapshot, configure about 256 or 512 MB RAM, enable IPFW3 (I used the basic and layer4 modules), and continuously download/upload some data.  Also keep monitoring the mbuf usages (netstat -m).

I will set up a VM to test this issue and report to you.

P.S., my home DFly machine just freeze (no response and cannot reboot by pressing Ctrl+Alt+Del) after (about several seconds) loaded the ipfw3_basic.ko kernel module.  It used to be OK.  Do you have any ideas or suggestions to investigate this?  Or I will just upgrade to the latest master and try again.
