You were experiencing SOS above the line. The region was found to contain muliple CEMT task all waiting on storage. You are receiving DFHZC2404 (VTAM detected an error in a request) followed by: DFHZC0001 An abend (code ---/AKEG) has occurred at offset X'2BFE' in module DFHZGTA. CICS then continued with repeated with 0C4 in DFHZGTA: DFHZC0001 An abend (code 0C4/AKEA) has occurred at offset X'FFFF' in module DFHZGTA. As the errors continued, there was also an AKEG in DFHTBSB DFHAP0001 An abend (code ---/AKEG) has occurred at offset X'00000AFA' Then, later, you received the failures in MVS GETMAINS. DFHME0006 Insufficient storage to satisfy GETMAIN (code x'0342') in module DFHMEME. MVS code 0004. The region eventually has to be cancelled. . ZC0001 dump shows the task running in error is CATA. . Looking into the last abend0C4/AKEA. Program DFHZGTA was in control, but the PSW was elsewhere. Error happened under the CICS RB. .

Further diagnosis, the problem is that CICS picks up a bad value of KERNPOWN in DFHZGTA HCI6700 at offset x'330' for CATA. This leads to abend0C4 at offset x'33C' where we did 0B0E or BSM 0,14 r14: A0000_000150E1 contains an invalid branch address. . Additional Symptom(s) Search Keyword(s): KIXREVSWM

Problem summary
**************************************************************** * USERS AFFECTED: All CICS users. * **************************************************************** * PROBLEM DESCRIPTION: Abend 0C4 occurs following an abend * * when DFHZGTA is in control. * **************************************************************** * RECOMMENDATION: * **************************************************************** An abend occurs when DFHZGTA is running. This results in the recovery routine being driven. On exit from the recovery routine, control is passed to the module exit point. If register 11, which is used as a saved stack address, has become invalid, DFHZGTA will experience an 0C4 abend.
Problem conclusion
DFHZGTA has been changed so that the saved stack address is correct before control is passed to the module exit point.
