op. sys. refuses to provide memory
Stata's data-storage memory manager has already allocated 1664m 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.
