The apache instance ends.

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.
