  This is very old problem, but where, that I haven't been able to
  locate, as I see it so damn rarely myself.

  And it is a beauty-wart, not real system threatening thing, that
  is why I havent' burned very much effort there (of lately).

  Do you see any odd things mentioned at your  $LOGDIR/scheduler ?
  Of the machine which has the decrementing counters ?
  I would like to know which part of the internal book-keeping is
  doing double-free, or some such.  (To have even some *hint* at it!)

  Damn, I forgot to mention that at the README.UPGRADING.
  I have aspired to move all ZMailer system local files to  $MAILSHARE/
  (if shared by all nodes), and to $MAILVAR/ (if node local).
  This time around the  zmailer.conf  got moved to $MAILSHARE/, and
  mail.conf   to  $MAILVAR/.
