Monitoring not robust enough

If a monitoring message cannot be sent then the Timer thread dies and the application never attempts to send any more messages. In the case below, the message could not be sent because the queue was full. Restarting the GUIApplication emptied the queue but the client applications had all stopped sending messages. This can be fixed with a try/catch loop in the relevant run() method.
