RE: Pointer not set for location referenced.

["Eric Wolf" <eric_a_wolf@xxxxxxxxxxx>]

  Eric,

  For one of the programs, I am using a named activation group.  For the
  modules that seem to be having the problem (which are in the service
  program), I am using *CALLER with a Shared AG(*NO).

  I was thinking along the same lines that maybe somewhere a RCLACTGRP was
  being called but I not using that command anywhere.  We are running MAPICS
  ERP software which (primarily) is not written in ILE.

  I was thinking of changing the one program from the named AG to *CALLER.

    >Are any of your apps trying to reclaim activation groups?  You use
    *Caller for all your ILE modules, but you didn't say whether you use
    named AGs or *NEW.  In any case, it sounds like parts of your app are
    being reclaimed, leaving the still active parts with invalid pointers.
