An established connection was aborted by the software in your host machine

I am fetching data using tiny tds. While fetching am getting following error. Am not using eclipse. Am using Mongrel server + Windows

     Read error: #<Errno::ECONNABORTED: An established connection was aborted by the software in your host machine.>

Please suggest me how to resolve this issue.

Solution

I have the same problem: the server log has this error message and client gets Timeout exception. Finally we got the root cause: we send base64-encoded string of an image from the web server to the client. This base64 string may interrupt with the separator codes of the HTTP response and crash the web server. After we removed the base64 string, it works fine.
