Error description
DUMP TITLE=xxxx,ABN=5C6-00E20001,U=SYSOPR,C=R3600.710.SMC -CSQSGSTG,M=CSQGFRCV,LOC=CSQSLD1 .CSQSVBK +000014F2 CSQY291E CSQWDSDM SDUMPX FAILED,RC=00000B08,xxxx, ABN=5C6-00E20001, LOC=CSQSLD1.CSQSVBK +000014F2 CSQV086E QUEUE MANAGER ABNORMAL TERMINATION REASON=00E50717 Problem is different from that reported by PI60582. . The problem here occurs when CSQMCIG1 (groupur indoubt processor) is trying to read a peer's logs. A log record has been read by CSQJPPLG which is larger than the current buffer size. so return code 00D10321 has been received. CSQJPPLG then releases the current buffer, but then references it again to see the size of the log record. However, the buffer storage has been reused which results in CSQJPPLG requesting a zero length buffer, which results in the 5C6-00E20001 abend being issued.

Problem summary
**************************************************************** * USERS AFFECTED: All users of WebSphere MQ for z/OS Version 7 * * Release 1 Modification 0. * **************************************************************** * PROBLEM DESCRIPTION: Shared queue managers using group units * * of recovery (GROUPUR) can generate * * abend 5C6-00E20001 in CSQSVBK followed * * by an abnormal queue manager * * termination with error message CSQV086E * * and reason 00E50717. * **************************************************************** * RECOMMENDATION: * **************************************************************** While CSQJPPLG is reading log records from other queue managers in the QSG, it can pass an invalid buffer length to CSQSVBK to allocate buffer storage resulting in abend 5C6-00E20001. The queue manager abnormal termination is caused by the recovery routines in CSQJPPLG and CSQMCIG1 not returning to the recovery termination manager (RTM) to complete the recovery process.
Problem conclusion
CSQJPPLG has been changed to save and pass the correct buffer length to CSQSVBK. Error recovery exit routines in CSQJPPLG and CSQMCIG1 have been corrected to return back to RTM. 100Y CSQJPPLG CSQMCIG1
