op. sys. refuses to provide memory
    Stata's data-storage memory manager has already allocated 11808m bytes
    and it just attempted to allocate another 32m 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.
64位操作系统，加了内存条（8gb）为什么还是打不开dta数据（17866701kb），求助!!!
