    A log offload was scheduled, but failed (for example, unable to
    allocate an archive log dataset), and the offload was scheduled
    to be retried after a short interval.
    Prior to the offload being retried, the queue manager was
    shutdown, and the RMBG control block was freed.
    When the offload subsequently retried, CSQJOFF1 attempted to
    reference the freed RMBG, leading to the reported abend 0C4.
    

Problem conclusion

  • CSQJOFF1 is changed to avoid referencing the RMBG if queue
    manager termination is sufficiently advanced that this control
    block could have been freed.
