It appears this error is only emitted when the server tries to send a message to a client which has not properly closed its WebSocket connection. Messages are successfully sent to open WebSockets.
The ReopeningWebSocket class on the client side appears to call WebSocket.close() on the beforeunload event, and groups_controller is meant to terminate WebSockets which haven't received a ping response in 30 seconds.
It's a bit tricky to test whether this is all working correctly, but if it is then I'm not sure there's much more we can do to prevent these errors.
