When the Prediction Engine is working on a feeder, it locks that feeder in the geodatabase until it is finished predicting. Should the application close prematurely or fail for some reason, that feeder may remain locked in the geodatabase even though Prediction Services is no longer analyzing it. The FeederExpirationInMinutes setting determines a set amount of time a feeder may remain locked in the geodatabase. After this amount of time the lock on the feeder is released and Prediction once again has access to predict upon it. By default, this expiration time is set to 5 minutes. To change this amount of time, follow the steps below.

1. Open Miner.Responder.PredictionServices.exe.config. By default, this file is installed here: C:\Program Files (x86)\Miner and Miner\Responder\Server.
2. Look for the following XML:

   	Copy Code
   <add key="FeederExpirationInMinutes" value="5" />

3. Change the value attribute to the amount of time (in minutes) after which the feeder lock is released.
4. Save and close Miner.Responder.PredictionServices.exe.config.
