Streamie.org was crashing constantly with a message that in line 23 of websocket.js this.connection did not have a method of "setTimeout"
Because this was the production system I added a line
if(!this.connection.setTimeout) return;
This works around the server-crash issue for me.
I now get this constantly
3 Sep 14:31:07 - Initializing client with transport "websocket"
3 Sep 14:31:07 - WebSocket connection invalid
I suspect a faulty client is reconnecting all the time.
