Really insufficient information to properly diagnose. Need the call  
stack of the job and rest of job log. Still, let's see what analysis  
shows . . .

MCH3402 means code tried to use a resolved pointer but the object to  
which it refers is destroyed (deleted). One frequent cause is running  
code in the DFTACTGRP that refers to "stuff" in another activation  
group that no longer exists.

However, the message is sent from the QLEAWI service program. That  
*SRVPGM contains the routines for the various CEE APIs. The module  
that sent the message is QLETREC which is suspiciously like the name  
of CEETREC which is the API to perform a Normal End of Activation group.

So, is your code running in the DFTACTGRP? If so what references are  
you keeping to "other stuff"?

Does your code call the CEETREC API? Or any of the other CEE  
Activation Group and Control Flow APIS?

Does your code explicitly use activation groups? Are you 'managing'  
these or letting the system do it?

Can you get the call stack at the time of failure? If so is your CGI  
program in the stack?

No answers but plenty of things to investigate further.

Simon Coulter.
