Problem summary
**************************************************************** * USERS AFFECTED: All users of WebSphere MQ for z/OS Version 8 * * Release 0 Modification 0. * **************************************************************** * PROBLEM DESCRIPTION: Abend 5C6-00E50076 occurs in CSQVEUS1, * * followed by abnormal queue manager * * termination with REASON=00E50706 when a * * CICS task abends while waiting for an * * execution switch to complete. * **************************************************************** * RECOMMENDATION: * **************************************************************** A CICS transaction was abended while suspended in CSQVEUS1 waiting for an execution switch to occur. CSQVEUS1's recovery routine set the EBDR flag to indicate that deferred recovery was required before percolating. CSQMCPRH's recovery routine then executed and checked whether EBDR had been set, however because the CICS transaction was running on a different EB to the connection EB, the wrong EB was checked. This led CSQGFRCV to incorrectly retry rather than percolating. When the CICS transaction subsequently went though termination processing, the unexpected retry left the ACE in an invalid state, leading to CSQVEUS3 attempting to suspend on a ROB that had already been suspended on, and resulting in the reported abend.
Problem conclusion
CSQGFRCV is changed to correctly handle the case where a CICS transaction running under a EB other than the connection EB has abended and EBDR has been set. 000Y CSQGFRCV
