Luc - See the IBM web site for that msg.  APAR IC37437 instated the msg and its
      revision to the space estimation methods, supposedly to be fully included
in the 5.2.2.0 you are running.  However, I see that there is also a subsequent
"fudge" evidenced in swg21165187 which you may have to pursue.  Sigh.
