Error description

  • After an ABEND5C6-00C93100 in CSQIEXP2+003051 the Queue Manager
    terminates with CSQV086E reason code 00E50705.
    
    The QMGR terminates due to CSQIEXP2's PRR not releasing the IKR
    synoymn chain latch.
    
    This APAR is going to solve the second problem.

    ****************************************************************
    The initial abend occurs when expiry processing on an indexed
    queue is unable to find and delete the IKR associated with the
    message being expired. This leads to the modules recovery
    routine to be invoked, which, as the IKR was not deleted,
    attempts to call the same procedure again to find and delete the
    IKR. This again fails, issuing a second 5C6-00C93100 abend. As
    this occurs in the recovery routine, it leaves a latch held
    within the module, resulting in the termination of the queue
    manager.
    

Problem conclusion

  • The recovery routine in CSQIEXP2 has been corrected to not call
    the procedure that attempts to find and delete the IKR if the
    recovery routine was invoked as a result of an abend issued
    by this procedure. This will stop the second abend being issued
    allowing the latches held to be freed, preventing the queue
    manager termination in this scenario.
