Heartbeat Signal
When an Autodesk product is running, it communicates with the license
server at regular intervals using a communication method known as the
heartbeat signal. If the heartbeat signal is lost, the server tries to reconnect.
If the server cannot reconnect, the user receives a license error.
If the product stops working because it has lost a connection to the server,
you must shut down the product, and then restart it. If the problem causing
the original loss of the heartbeat signal is resolved and there are available
licenses on the server, the program can be restarted.
