Problem summary
**************************************************************** * USERS AFFECTED: All users of WebSphere MQ for z/OS Version 7 * * Release 1 Modification 0. * **************************************************************** * PROBLEM DESCRIPTION: Abend 5C6-00E50079 occurs in CSQEDEL2 * * following an application abend. * * The 5C6 abend is followed by CSQV086E * * QUEUE MANAGER ABNORMAL TERMINATION * * REASON=00E50054 * **************************************************************** * RECOMMENDATION: * **************************************************************** During MQCLOSE processing for a shared dynamic queue, an application was canceled while waiting for the structure task to complete a CSQE_OPEN_DELETE request and resume a ROB. The storage containing the address of the ROB was freed during recovery processing and subsequently reused. When the structure task completed the request, it attempted to resume the ROB, but due to the storage reuse the ROB address was no longer valid. This was detected by the resume code, leading to the reported abend and subsequent queue manager termination.
Problem conclusion
CSQIDDEL is changed to allocate storage that will not be freed during recovery to contain the address of the ROB, ensuring that the structure task can correctly locate the ROB to resume. 100Y CSQIDDEL
