Sure, I'll try to go into some detail:
1. the user starts a guacamole session which uses a websocket connection
2. as soon as the settings window is opened and there is an error in the
backend (e.g. database server offline) the fatal error message appears
3. although the user is no longer able to use the remote desktop, the websocket
connection remains open until the tab is closed (see screenshot)
4. if the user leaves the tab open and starts a new connection, the old stab
still consumes server resources

> Close websocket connection on fatal error

> Key: GUACAMOLE-1472
> URL: https://issues.apache.org/jira/browse/GUACAMOLE-1472
> Project: Guacamole
> Issue Type: Improvement
> Components: guacamole-client
> Affects Versions: 1.3.0
> Reporter: Marco Kittel
> Priority: Minor
> Attachments: Guacamole_Websocket_Fatal_Error.png
>
>
> Currently, when a fatal error occurs, an existing websocket connection is not
> closed.
> As long as the user does not close the Guacamole tab, the connection remains
> established and data continues to be transferred and server resources are
> used.
> After the error has occurred, it should be additionally checked whether the
> connection is still open and if so, it should then be closed.
