    .
    The failing instruction is 42A0 300F with Reg3=00000000.
    .
    The 0C4 happened when an ABENDS13E occurred while CSQMCTXE was
    in the middle of end-context processing. In this case, it was
    while a connected WebSphere Application Server was ending. The
    queue manager remained running.
