Hi there. I have an application using ws and express. When spam refreshing a page, this error will occur:

Error: write EPIPE
    at exports._errnoException (util.js:1050:11)
    at WriteWrap.afterWrite [as oncomplete] (net.js:814:14)

I have established that the issue is being caused by the library ws, but I have not reported this issue there as there is no evidence in this stack trace to suggest it is being caused by this library. The error seems to be exclusively produced by this snippet:

ws.broadcast = (data) => {
  ws.clients.forEach((client) => {
    if(client && client.readyState === WebSocket.OPEN) 
      client.send(data);
  });
};

Thanks.

Can you post support questions to https://github.com/nodejs/help/issues? EPIPE means the other end closed the connection. That's something your application (or ws) needs to handle, node.js core just passes on the event from the operating system.

It looks like you are using Jsmpeg library like me. you can add code

   socket.on('error', function(e){	
	console.log(e)
   });

to the WebSocket server.

I have tested it. The server runs ok.
