Error description
Change Team finds that the ABEND0C4 in CSQWVZSS occurs as its recovery routine is not setting up addressability to the WWAB when processing an abend.
Local fix
The problem can be circumvented by stopping the collection of queue manager statistics records: STOP TRACE(STAT) DEST(SMF) If the queue manager might be restarted before the fix for this APAR is applied, include that command in a CSQINP2 member or set SMFSTAT=NO in CSQ6SYSP.
Problem summary
**************************************************************** * USERS AFFECTED: All users of WebSphere MQ for z/OS Version 8 * * Release 0 Modification 0. * **************************************************************** * PROBLEM DESCRIPTION: Abend S0C4 may occur in CSQWVZSS * * during recovery for another abend. * * Following this secondary abend, the * * queue manager can hang during * * shutdown processing. * **************************************************************** * RECOMMENDATION: * **************************************************************** If a system abend occurs in module CSQWVZSS while capturing SMF statistics data, the recovery routine may not correctly establish its base registers before performing recovery processing. This may result in an S0C4 abend occurring and masking the true cause of the underlying abend.
Problem conclusion
Processing has been amended to ensure that recovery processing establishes its base registers correctly and the underlying abend is correctly reported. 000Y CSQWVZSS
