Error description

  • Insert of deleted rows during abort got DSNIBHUN:500F because

    ****************************************************************
    Insert uses the space that is marked deleted, but the space
    is released incorrectly by a child task from the same UR
    that did the delete.
    

Problem conclusion

  • Code is changed to consider conditions from child tasks before
    marking a space is reusable.
