Error description
Your region is at SOS above the line, then you receive following message, MESSAGE: DFHSO0001 An abend (code 0C4/AKEX) has occurred at offset X'1D4E' in module DFHSOSE. SYMPTOMS: PIDS/5655Y0400 LVLS/680 MS/DFHSO0001 RIDS/DFHSOSE PTFS/UI33707 AB/S00C4 AB/UAKEX ADRS/00001D4E . The trace shows the following, SM 0302 SMGF EXIT - FUNCTION(GETMAIN) RESPONSE(PURGED) REASON(INSUFFICIENT_STORAGE) ADDRESS(00000000) . It appears there is an issue in CICS code in DFHSOSE UI33707 where the task was requesting GET_LENGTH(1470) for SOGENRAL of ECDSA storage, since CICS has no more ECDSA storage left at the dump time, the GETMAIN request was purged/x'06'. However, CICS is still trying to loop through the code at 01D0E to add each buffer list to the storage we have never gotten. This leads to the abend0C4 issue.

Problem summary
**************************************************************** * USERS AFFECTED: All CICS users. * **************************************************************** * PROBLEM DESCRIPTION: Abend0C4 in DFHSOSE after CICS Short * * On Storage condition. * **************************************************************** * RECOMMENDATION: . * **************************************************************** CICS goes Short On Storage and enters stall purge (SPURGE) and deadlock-timeout (DTIMEOUT) processing to purge eligible tasks. If DFHSOSE is in a suspended GETMAIN, waiting for the SOS condition to end, then it is purged. DFHSOSE does not handle the PURGED response correctly, and tries to use a null GETMAIN pointer, resulting in an 0C4 abend. Keywords: AbendS0C4 S0C4
Problem conclusion
DFHSOSE has been changed to process the PURGED response from its GETMAIN call correctly.
