Problem summary
**************************************************************** * USERS AFFECTED: All CICS users. * **************************************************************** * PROBLEM DESCRIPTION: DFHIE0001 An abend (code 0C4/AKEA) has * * occurred at Offset X'0736' in module * * DFHIEIE, this abend is preceded by * * later an AITH abend. * **************************************************************** * RECOMMENDATION: * **************************************************************** CTG was used to send ECI request to CICS. When a CIEP task was processing an connection closed , a mirror task processed a SEND LAST and attempted to delete the same conversation IECCB too. If this IECCB got reused by a different connection which came in after SEND LAST completed and IECCB freed. CIEP can end up corrupting the reused IECCB and purge the task related to this reused IECCB. This led to an AITH abend of new task and 0c4 error when attempting to access the IECSB from the corrupted IECCB.
Problem conclusion
DFHIEIE has been changed to avoid corrupting an IECCB when a connection closure happens.
