Subject: `sysread' end of file reached `rbuf_fill' problem

when my problem is using multithreading to get some documents from www
server through net::http library. The code is as follows


Net::HTTP.start(url.host) do |http|
req = Net::HTTP::Get.new(url.path, {"User-Agent" =>
"Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; SV1; .NET CLR
1.1.4322; InfoPath.1)"})
response = http.request(req)
http.finish()
case response
when Net::HTTPSuccess
then return response.body
else
puts "Response Not Success"
return ""
end
end

I always receive errors as follows:

C:/ruby/lib/ruby/1.8/net/protocol.rb:133:in `sysread': end of file
reached (EOFE
rror)
        from C:/ruby/lib/ruby/1.8/net/protocol.rb:133:in `rbuf_fill'
