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.
