RE: Pointer not set for location referenced.

Eric,

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.

Subject: Pointer not set for location referenced.


   To the list,
   I have looked through the archives but cannot seem to find an explanation
   for what is occuring.  Here it is:
    
   My users are receiving this error MCH3601 Pointer not set for location
   referenced on different programs during the day.  All the programs are
   using modules of a service program to retrieve a single record from a
   file.  Each module is being passed the external datastructure of the file
   to be retrieved and the datastructure is being cleared and the key fields
   are being reset before each execution of the module.  They pretty much all
   look something like this:
    
   /free
   ...
   clear carrier;
   carrier.id = ordcarrier;
   carrier = RtvCarrier (carrier);
   ...
   /end-free
   Every once-in-a-while, the error appears when attempting to execute the
   RTVCARRIER statement. After receiving the error message, the users sign
   off and back on again and all is fine.  None of the modules have changed
   and new modules are added to the end of the SRVSRC BND
   member. The programs that are "calling" the modules are compiled with the
   ACTGRP(*CALLER) 
    
   Any suggestions as to where to focus my attention would be greatly
   appreciated...
    
   TIA,
   Eric A. Wolf
