A really good tool for stress-testing a system is ports/math/mprime.  It
will find memory and cpu errors that memtest86 and other tools
completely overlook.  Run one copy per cpu, something like this:

for i in $(jot $(sysctl -n hw.ncpu) 0) ; do
    sleep $((i * 2)) && mprime -t -a$i >/tmp/mprime$i.log &

Many overclockers use this to ensure the system is stable with the OC
settings.  If your system can run a copy of mprime per cpu continuously
for 24 hours the hardware is fine.
