Hi, I’m Mario.  
I try to send some data chunks to all participants using the session.signal function.  
With messages larger then ~32k the websocket/RPC stuff performs a reconnect and my message is lost.  
Is there a limit for signal message sizes or some other way to pass data to all others ?  
Is it a Bug ?

Steps to reproduce:  
Just paste some LoremIpsum into the chat form of an OpenViduApp. I used Docker to deploy one. I use version Openvidu Version: 2.15.0

The server log shows this :  
openvidu-server\_1 | [INFO] 2020-07-22 16:38:15,894 [http-nio-0.0.0.0-5443-exec-8] io.openvidu.server.config.HttpHandshakeInterceptor - Old HttpSession 4AC6308DA9835A2955773F7CE19450C8

WebSockets messages have a limit. I don’t remember right now, but maybe 32 kbytes. If you need larger messages, you will have to manage them on your application.
