I have set the crawler to sleep for a while (2 seconds) between each request to api.twitter.com. However, after some times of running (around 1), when the Twitter's rate limit not exceeded yet, I got this error. [Errno 10054] An existing connection was forcibly closed by the remote host. What are possible causes of this problem and how to solve this? I have searched through and found that the Twitter server itself may force to close the connection due to many requests. Thank you

My questions now are: Which conditions can lead to this type of IOError? What does it exactly mean? What does it mean for the subprocess that has been invoked by os.system() ?
