A connection was closed by the client when the server was sending
data.

This happens normally when you hit stop in your browser while the page
is still loading.

Without knowing if this is a crash or an intermittent problem on your
side we can't help you further.

1) Does this error stop the webserver from working?

2) That is the entire backtrace of your application?

3) This does happen randomly or you have a way to reproduce it?

4) Does it reproduce on a clean application or just your application?
