Error description
MQ ABEND0C4 in CSQWVZSA due to an ABEND653 in SMF because of lack of storage in the CHIN address space. During the processing of the abend, CSQWZSAF assumes that R9 contains the address of the WWAB control block, but that is not the case, hence the 0C4 occurs.

Problem summary
**************************************************************** * USERS AFFECTED: * * All users of IBM MQ for z/OS Version 9 Release 0 * * Modification 0. * **************************************************************** * PROBLEM DESCRIPTION: * * Abend S0C4 may occur in CSQWVZSA during recovery for another * * abend. * **************************************************************** * RECOMMENDATION: * * None * **************************************************************** If a system abend occurs (e.g. due to a storage shortage) in module CSQWVZSA while capturing SMF 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.
