You are running with CICS TS 51 and you are receiving the following message: DFHPC0409 ABENDS AZTA AND AZTA HAVE BEEN ISSUED WHILE PROCESSING ABEND AZI3 FOR THE SAME TASK, TRANSACTION CEDF. . The involved task is CEDF. The kernel error table shows multiple percolate abends starting with AZTS's, AZI3's, then AZTA's which causes a DFHPC0409 and CICS is terminated. . Further investigation, found that the trace shows data area 1 is the parm list passed to DFHXMIQ. There is nothing in the word at +x'10' XM 1001 XMIQ ENTRY - FUNCTION() TASK-00086 KE_NUM-00F7 TCB-QR /008CE598 RET-95CFB77A TIME-00:05:40.3246302846 INTERVAL-00.0000004062 1-0000 01100000 000000A1 00000000 00000000 00000000 00000000 03000100 00000000 <<<<<<<< XM 1002 XMIQ EXIT - FUNCTION() TASK-00086 KE_NUM-00F7 TCB-QR /008CE598 RET-95CFB77A TIME-00:05:40.3246309721 INTERVAL-00.0000006875 1-0000 01100000 000000A1 00000000 00000000 00000000 00000000 03000100 00000000 <<<<<<<< The problem happen because REGISTER 2 and REGISTER 7 have been corrupted when the KERNEL has called DFHEDFP recovery routine at label ABNDHAND. Registers 2 and 7 are used as DFHEDFP base registers and address static storage. . In the expension of the DFHXMIQM macro, register 2 is used to set XMIQ_EXISTENCE bits which will be set incorrectly resulting in the terminal not being removed from the CEDF task. .

Problem summary
**************************************************************** * USERS AFFECTED: All CICS users. * **************************************************************** * PROBLEM DESCRIPTION: DFHPC0409 abends AZTA and AZTA have * * been issued processing abend AZI3 * * for the same task. * **************************************************************** * RECOMMENDATION: * **************************************************************** The original problem was reported against CEDF in a TOR running a transaction in an AOR when the TOR used a non-zero RTIMEOUT value in single terminal mode. Exceeding the RTIMEOUT value results in an AZI3 abend in the AOR, and the recovery routine in DFHEDFP is entered. The addresses in registers 2 and 7 that are used to address storage are not valid, and when register 2 is used in a subsequent DFHXMIQM macro, the terminal is not removed from the CEDF task, which results in the AZTA abends, which in turn cause the PC0409 abend and the AOR is terminated. The CEDF session in the TOR shows an abend, but the TOR is not terminated. Additional keywords: MSGDFHPC0409 abendAEDG 030F SM0002 msgDFHSM0002 PI18848
Problem conclusion
DFHEDFP has been changed to correct the error in its recovery routine.
