You probably want to look _at_ turning on crash-dumps
(rc.conf, set dumpdev), making sure you have enough swap
to hold all physical memory, and then debugging the
core that comes out.

http://www.freebsd.org/doc/en_US.ISO8859-1/books/developers-handbook/kerneld
ebug.html
has instructions.

If you post back a stack trace from this process,
