Dump Title: CICS SYSTEM DUMP - REQUESTED BY DFHXSS
The dump is for an abend0C4 in module DFHXSSB. You are running with CA ACF2.
DFHXSS takes a system dump with an abendS0C4.
The structure that DFHXSSB is traversing was built incorrectly by CA ACF2.

Diagnosing the problem
DFHXSSB was called for INQ_PASSWORD. This results in the following racroute request:
RACROUTE REQUEST=EXTRACT, Perform Extract service
TYPE=EXTRACT, Just retrieve profile fields
FIELDS=INQ_PASSWORD_FIELDS, List of required fields
WORKA=SAF_WORKAREA, Address of SAF workarea
SUBSYS=ESM_SUBSYS, Subsystem identifier
DECOUPL=YES, Decouple from router table
RELEASE=7740, z/OS 1.9 or above
MF=(E,RACXTRT_AUTO) Execute form of macro
The extract completed succssfully and DFHXSSB calls the DETERMINE_REVOKED_STATUS routine. This routine involves CICS traversing the fields passed back in the extract. The 0C4 occurred during the DETERMINE_REVOKED_STATUS routine when trying to process the number of groups (group_count) the userid is associated to. The failing instruction is BFBF8000, which is an ICM. Register 8 (R8) points to an address that is not addressable.
