One thing a robot must do is read and follow the http://zh.wikipedia.org/robots.txt file ( probably you sould read it too) As a general rule of Internet, a "rude" robot will be banned by the site admins. It would be a good idea to anounce your bot as a bot in the user_agent string . Good bot beavior is one that read a website like a human. I don't know, like 10 request minute?. I don't know about this "Wikipedia" site rules about it. What you are suffering could be automatic or manual throttling, since is detected a abusive number of request from your IP. "Wikipedia" seems to provide fulldumps of his wiki, but are unusable for you, since are giganteous :-/, trying to rebuilt wikipedia on your PC with a snapshot would be like summoning Tchulu in a teapot. But.. I don't know, maybe the zh version is smaller, or your resources powerfull enough. One feels that what you have built has a severe overload (wastage of resources) and there must be better ways to do it...
