Setting the number of maximum concurrent WebSocket

[Matthieu Ravey]

Hi,

My app is using websockets and when I tried to deploy it and have more than 4 concurrent connections I got those exceptions :

java.io.IOException: Broken pipe

I think there is something to set in the configuration to handle more concurrent connections, but I did not find it in the documentation. 

Thank you for your help.

Any help ?

There is no limit. Apart if your websocket implementation is blocking
so you will quickly block all threads and new connections will be
rejected.
