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.

    *                      terminate with REASON=00F30409 or       *

    ****************************************************************
    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.
