Take a look at chapter 17 of the developers handbook: http://www.uk.freebsd.org/doc/en_US.ISO8859-1/books/developers-handbook/kerneldebug.html You want to save a crash dump when you get another one of these panics, that you can analyse later with gdb to find out exactly where it's crashing. I shouldn't speculate on causes until you have more idea what's happening, but this does smell like failing hardware. In your position, I'd be thinking about swapping RAM and maybe the power supply.
