    (1) IHVUOINM traces the XRCBs at the end of the command
    processing. However, the trace is done after IHVUOXMM is
    called which sets up an SRB that posts IHVUUSDM which in
    turn moves the data back to the user address space and
    deletes the XRCBs.
    
    (2) IHVLFMT failed to store a formatted message into the
    message table. This is caused by an improper address of
    the message table stored in the SRB parameter list. The
    SRB is scheduled when an IOOps command is issued using
    the IHVAPI interfaces.
    

Problem conclusion

  • (1) The trace has been moved ahead of the call to IHVUOXMM.
    
    (2) The SRB and the IOOps task UOBY use BASETBSY as input
    for a CS instruction. Since they run on different tasks both
    can proceed but the last gets an updated BASETBSY value. This
    results in two POSTs to IHVUOINM.
    
    The address in the SRB parameter list has been corrected.
    
    In addition, the storage area of the message table is now
    released together with the appropriate XCCB and XRCB control
    blocks. This caused a storage leak every time an IHVAPI command
    was executed. add'l keywords: storage growth out of storage
