Explains license server errors that require the restart of an Autodesk product.
When an Autodesk product is running, it communicates with the license server at regular intervals using a 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 license server, you must shut down the product, and then restart it. Most Autodesk products give you the opportunity to save open documents before shutting down. If the problem causing the original loss of the heartbeat signal is resolved and licenses are available on the server, you can restart your Autodesk product. If you are running several Autodesk products when a license server connection is lost, the error messages for different products typically appear after different time delays, based on product settings.
In 2016 and later releases only, you can disable cascading by setting the value of the environment variable ADSK_CASCADING_OVERRIDE to 0 (disabled). (A setting of 1 enables cascading.) This setting applies across all products. Cascading is automatically disabled for Autodesk Enterprise Token Flex (using product code 535H1) regardless of the setting.
