Hi,
Just to follow up. It seems that the there is a 15 minutes timeout for
WebSockets on the server side as well. I'm running my own
WebSocketApplication (I'm using grizzly-http-server-2.2.21.jar and
friends, and I'm using code very similar to the example in the WebSocket
chapter of the documentation), accepted a connection from the client.
After 15 minutes, the onClose() call back is called from a thread named
"HttpServer-0" with the following stack trace.
I'd appreciate it if someone can let me know how to turn off this
timeout off as well.
