    ****************************************************************
    In deferred put processing when a message is initially put to
    the SYSTEM.PENDING.DATA.QUEUE, an IKR (index key record) is
    created for the message. Since it is indexed by CONNID the
    index uses just the first 16 bytes of the IKR.csKey instead of
    24 bytes as for the majority of indexes.The last 8 bytes may
    not be zeros
    When the deferred message is subsequently processed, CSQIMGE1
    checks that the IKR and message are consistent. In this case
    they don't match since there is residual data in IKR.csKey and
    so the abend occurs.
    

Problem conclusion

  • Code has been changed to ensure IKR.csKey is initialised before
    use in this case.
