用stata12 打开一个1.7G的数据，结果出现如下提示：op. sys. refuses to provide memory
    Stata's data-storage memory manager has already allocated 1760m bytes and
    it just attempted to allocate another 16m bytes.  The operating system
    said no.  Perhaps you are running another memory-consuming task and the
    command will work later when the task completes.  Perhaps you are on a
    multiuser system that is especially busy and the command will work later
    when activity quiets down.  Perhaps a system administrator has put a limit
    on what you can allocate; see help memory.  Or perhaps that's all the
    memory your computer can allocate to Stata.

请教各位大神，如何解决？谢谢了。
