I've been using IPF 3.4.20 on FreeBSD since 3.4.20 came out.  I'm 
currently running two of my firewalls with IPF 3.4.20 on FreeBSD 
4.4-RELEASE while four other FreeBSD firewalls with IPF 3.4.20 on 
FreeBSD-STABLE 18 days ago with 18 days of uptime.  All of my firewalls 
use ipmon -s.

Can you capture a core dump or break into kernel debug mode as the 
system panics?

Are you logging to syslog or to a file?

Is it possible that ipmon is exercising a flaw in your hardware, e.g. 
faulty memory?
