Error description
Problem happens if there is a storage violation and dumpcode SM0102 is defined with option SHutdown. A dump is taken for the SM0102 and CICS begins to terminate. However, during shutdown we see DUMPCODE: KERNDUMP, DUMPID: 0/0000. (MODULE DFHKESTX) and the Job completes with CICS - ABEND=S0C1 U0000 REASON=00000001 The KERNDUMP is for an abend0C1. DFHKETCB is entered from DFHKESTX with reg6 pointing at the KE stack and not the base address for DFHKETCB. DFHKESTX was entered with a SWDA for a loop U999 (3E7). KE dump error table has AKEG abends on the KTCB for QR, RO and STEP TCBs: KE_NUM ERROR TYPE ERR_CODE MODULE OFFSET ====== ========== ======== ====== ====== 0002 LINKAGE ---/AKEG DFHKETCB 000027BA 0003 LINKAGE ---/AKEG DFHKETCB 000024D0 0001 LINKAGE ---/AKEG DFHKETCB 0000213E 0001 ABEND ---/0999 DFHKERPC 00000172

Problem summary
**************************************************************** * USERS AFFECTED: All CICS users. * **************************************************************** * PROBLEM DESCRIPTION: ABEND 0C1 during shutdown if CICS * * termination is triggered by the * * shutdown option of dumpcode SM0102. * **************************************************************** * RECOMMENDATION: * **************************************************************** SM0102 is specified with shutdown option in the user's CICS region. A user task encounters storage violation. At the end of the cleaning up of the task, DFHSMAR obtains the SM domain lock and issues the SM0102 message. This message triggers system termination. During system termination, some CICS TCB tasks may need to acquire storage but they would fail due to being unable to obtain the SM domain lock. This eventually causes the system to terminate with abend code 0C1. Additional keyword: S0C1 ABEND0C1 ABENDS0C1
Problem conclusion
DFHSMAR has been changed so that the SM domain lock is released before SM0102 message is issued.
