Websocket session closing

[kjella]

Using version 4.1.2-rc.3-SNAPSHOT I get the following exception after a couple of hours running the bot:
java.lang.IllegalStateException: Message will not be sent because the WebSocket session has been closed

Here is the complete stack trace:

Just updated my original issue with all the logging statements regarding the IllegalStateException.
