Please help me to identify the root cause..

Answer 1

Well, BROKEN PIPE is usually an informative message from you server telling you that it tried to answer a request, but there was nobody to listen.

It happens when the requester timed out, or if a human with a browser by example refresh the page before completion.

Although normally not a problem per se, it could be, in some circumstances, the symptoms of a network problem, a capacity problem or any other problem that affect the amount of time the server takes to answer a request.

Without more details about your set up and the application this stacktrace is reffering to it's difficult to more precise though.

Answer 2

'Broken pipe' errors usually occur when the browser is closed before the request can be completed. They are harmless. There are various reasons, but the most common being a browser session being closed while the request is still processing.
