The change in memory consumption in the step termination reports would suggest that memory acquisition is varying with region size in this case. The fact that there is no S80A, S878, etc., abend would indicate that something inside the application knows how large the region is and does not exceed its bounds.

It would be interesting to know the final cause and resolution. -- Regards, Dave [RLU #314465] *-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-* [email protected] (David W Noon) *-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-* ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
