The SAS Analytics Platform Server uses a long polling mechanism to minimize network traffic. In long polling, the client side holds a network connection open while the network is in a hold status. In some network environments, the connection is closed (for example, by a firewall timeout), and the client of the SAS Analytics Platform fails.

When the connection is closed, the following dialog box appears in the SAS^® Warranty Analysis rich client:

The only option is to click OK and then restart the rich client.
