In SAS^® Forecast Server, when you re-forecast your SAS Forecast Studio project, you might encounter one of the following symptoms:

• SAS Forecast Studio stops responding, and a message is displayed in the interface:

• SAS Forecast Studio stops the re-forecasting process, and an error is displayed in the SAS log:

• SAS Forecast Studio stops the re-forecasting process, and an error is displayed in the SAS log:

The problem occurs when you have a transfer function in an ARIMA model that meets the following conditions:

• The transfer function is one of multiple transfer functions in the ARIMA model.
• The transfer function is not the first transfer function that is specified in the ARIMA model.
• The order of the denominator polynomial for the transfer function is sufficiently larger than the other polynomial orders (including AR and MA polynomials) in the ARIMA model.

To circumvent the issue, take any of these actions.

• Delete the ARIMA model with the transfer function.
• Remove the input variable with the transfer function.
• Modify the orders of the denominator polynomial for the transfer function.
