Error description

  • The sanity check is to validate the low level space map page
    boundary before extension of the new cluster. However, in this
    case there are mix of the information and cause the logic that
    was intended for insert also being triggered. The load phase
    of migration REORG acts like a normal insert to load data into
    the new LOB table space.  This is not expected by the space
    allocation. Therefore, the performance code was exercised to
    read just the last entry of the low level space map page,
    therefore, the sanity check is triggered.
