呜呜呜呜，工企数据库打不开，系统显示下面这一串，怎么办呀<br>
op. sys. refuses to provide memory<br>
    Stata's data-storage memory manager has already allocated 1408m bytes and<br>
    it just attempted to allocate another 16m bytes.  The operating system<br>
    said no.  Perhaps you are running another memory-consuming task and the<br>
    command will work later when the task completes.  Perhaps you are on a<br>
    multiuser system that is especially busy and the command will work later<br>
    when activity quiets down.  Perhaps a system administrator has put a<br>
    limit on what you can allocate; see help memory.  Or perhaps that's all<br>
    the memory your computer can allocate to Stata.<br>
