Error description

  • MQ started a scheduled SDUMP (multi-address space).
    It did not supply an ECB or SRB. The issuing task
    did not wait for capture to complete.
    .
    MQ allowed the TCB which issued SDUMP to terminate
    and the PSW/REGS area which MQ passed to SDUMP to be
    freed before dump capture has completed.
    MQ should be passing an ECB to SDUMP and waiting
    for it to be posted.

    * PROBLEM DESCRIPTION: Abend S0C4-11 occurs in                 *
    *                      IGC0005A.IEAVTSSE while taking dump and *
    *                      no dump is captured.                    *
    ****************************************************************
    * RECOMMENDATION:                                              *
    ****************************************************************
    During recovery processing for an abend, SDUMPX is invoked
    asynchronously with various parameters. During the asynchronous
    dump capture, one of these parameters may be accessed after the
    caller of SDUMPX has terminated, resulting in an S0C4 abend.
    

Problem conclusion

  • Processing has been amended to ensure CSQXDMPS waits for SDUMPX
    capture phase to complete before terminating.
