    * PROBLEM DESCRIPTION: Incorrect serialization in IARV64       *
    *                      PAGEIN processing which leads to        *
    *                      C0D-0F000301 ABENDs in IAXGI.           *
    ****************************************************************
    * RECOMMENDATION:                                              *
    ****************************************************************
    IARV64 REQUEST=PAGEIN processing incorrectly releases the RSMCM
    serialization lock. This allows multiple PAGEIN requests
    to run concurrently for the same page after an enablement
    opportunity, causing an ABEND C0D-0F000301 in IAXGI.
    

Problem conclusion

  • The serialization problem is corrected.
    The code in IARV64 PAGEIN is corrected such that it will
    not release the RSMCM lock erroneously.
