Error description
Loop occurs after CEMT SET PROG(*) PHA command. The CEMT task abends with message: . DFHLD0004 A possible loop has been detected at offset X'FFFF' in module DFHLDLD3. . If ICVR is turned off for the task, CEMT never finishes. CICS trace shows that the CEMT task processes a number of programs, then goes into a loop. The loop is in DFHLDLD3, proc CPE_EXPLODE, and MVS system trace shows that the range of the loop is DFHLDLD3 +x874 to x88E (base level). . The problem is that the APE +x28 (field APE_OLDER_APE) for a program points to itself. Problem occurs when modules are used out of the LPA. . Additional symptoms/search keywords: KIXREVxxx REFRESH_PROGRAM DFHAPATT APE_OLDER

Problem summary
**************************************************************** * USERS AFFECTED: All CICS Users. * **************************************************************** * PROBLEM DESCRIPTION: Loop in DFHLDLD3 after a CEMT SET * * PROGRAM PHASEIN and program is loaded * * from the LPA. * **************************************************************** * RECOMMENDATION: . * **************************************************************** It is possible to suffer an abendAEXZ following a CEMT SET PROGRAM PHASEIN (or NEWCOPY) if the program being the subject of the PHASEIN has been loaded from the LPA. The problem happens because code in DFHLDLD3 is browsing through the Active Program Elements ( APE ) but the chaining fields in the APE have been incorrectly updated to point to itself because of changes to the optimization level of the compiler. Additional keywords: APE_OLDER_APE APE_YOUNGER_APE
Problem conclusion
DFHLDLD1 has been changed to revert the level of optimisation.
