The most recent FreeBSD version we use on our production servers is
RELENG_4, for stability reasons. And since we have the patch from the
PR installed on all these servers we've never had this issue again.
This way, we of course can't say whether it would have happened again
without the patch.
As to a transitory bad memory issue, all our servers have ECC protected
memory, which makes hardware induced memory corruption at least very
unlikely, though not completely impossible.
