that question belongs on bind-users@isc.org, i suspect.  but i'll answer: if
you redirect the "update" and "security" categories to channel "null" then it
works like you want.  if there was demand, ISC would make a specific category
called "failed-updates" so that other security related events wouldn't have
to be nulled at the same time.

not all failed updates are spurious.  i recommend against this as a default.
