It's because the browser is closing the connection, that's what the wrapped exception means.  The user is either hitting the stop button or navigating away or the file you're writing is taking way too long to write out and the browser (or a proxy along the way) is closing out the socket before everything is written.

You probably need to run this csv process in a background processing queue of some sort.

Can anyone please suggest how to resolve this exception. I implemented a code which writes huge data to the csv file. I don't know why the connection is getting out.
