Just in case, I'd enable coredumps, maybe you'll get "lucky" and have 
something to look at:

dumpdev="/dev/ad0s1b" in rc.conf (adjust to your swap partition)

Also make sure you've built a kernel with debug symbols:

makeoptions     DEBUG=-g        in kernel config

Lastly, for problematic hosts in the past I've put together a quick shell 
script that runs a whole mess of stuff; a full ps, vmstat, netstat, etc. 
and writes it to a logfile.  I call it out of cron every five minutes. 
That way if something does happen and there's no coredump I can see if 
anything odd was happening before the crash.
