That just means it's dumping core.  You need to look a little
deeper for why it's doing so.

In this case, it's smashing its own stack while doing a bcopy()
(or some related function).  If that's not consistent, this
probably *is* a hardware problem.  If it's dependable, then maybe
not.  Try to track down commonalities in what the system is doing
when it panics.  If possible.
