What causes Error: This socket has been ended by the other party?

I'd like to know what can trigger the error below? It rarely happens for my app and is very difficult to debug/fix. Thanks!

Typically this is sent when another application (client, browser, etc.) closes the socket when you are still sending data to it from the server.

I've had it happen when my browser drops the connection to the server on the socket while I am writing data to it.

The readme section on handling errors is pretty solid for when sends throw exceptions.
