李琴 well.. thats webscrapping, that is a poor tecnique, one with lots
of errors that generate lots of trafic.
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...
