​That looks like an odd way to *ask* for help.
If you wanna *request* help, consider getting paid support.​ But even doing
that, that is rude...

What the error says is that the '*backend* closed connection
prematurely'... You should look into it when processing the crashing
request.

Based on the logs, for that request, nginx received different headers
depending on using either IE or Chrome:
*IE*
"GET /Stream.html?s=0&d=%22168.189.9.09%22&p=450&t=1399381478365 HTTP/1.0

Cookie? :o)
Look into your application in the backend which does not answer when some
conditions, the problem does not seem to come from nginx which forwards
requests to yourf backend.
