Error description
The queue-manager was terminated with CSQV086E REASON=00F3040A due to latch on the DQCH was not released. . SYMPTOM DESCRIPTION. ------- -----------. RIDS/NUCLEUS#L LOAD MODULE NAME: NUCLEUS. RIDS/IEAVEPS1 CSECT NAME: IEAVEPS1. AB/S06C6 SYSTEM ABEND CODE: 06C6. PRCS/00F3040A ABEND REASON CODE: 00F3040A. . CICS job terminated abnormally with S33E. At the time of the abend hit, the TCB was in the middle of processing an MQ API request, and CSQ5RXCF had been invoked and had performed an execution unit switch and was waiting for it to complete, and was holding a latch on the DQCH at the time. Recovery processing for the S33E took place, but the TCB had been in execution unit switch EBDR was set by CSQVUES1's recovery routine, which meant that CSQ5RXCF's PRR was not invoked, so the latch on the DQCH was not released. Subsequent processing for the termination of CICMTN11 detected that a latch was still held. Additional Symptom(s) Search Keyword(s):

Problem summary
**************************************************************** * USERS AFFECTED: All users of WebSphere MQ for z/OS Version 8 * * Release 0 Modification 0. * **************************************************************** * PROBLEM DESCRIPTION: If applications connected to a queue * * manager abend, the queue manager can * * terminate with REASON=00F30409 or * * 00F3040A. * **************************************************************** * RECOMMENDATION: * **************************************************************** The following are two scenarios where the problem occurs when there is an asynchronous abend of application (i.e. CANCEL) causing the reported queue manager termination with REASON=00F30409 or 00F3040A. 1- Application putting messages to a shared queue using a destination queue manager that is another member of the QSG and the application abends in the middle of checking the XCF state of the other QSG member can cause the queue manager to terminate. 2- Application putting messages to a local queue with a buffer pool that is too small and message CSQP020E is issued at the time when the application abends can cause the queue manager to terminate.
Problem conclusion
CSQVEUS1 has been updated to introduce a delay to give time to active threads to complete avoiding deferred recovery which allows the recovery clean up exits to be invoked. 000Y CSQVEUS1
