Hey, Has anyone seen this error before when making a Linq to SQL call?

Invalid attempt to call FieldCount when reader is closed

Here's the code:

public static MM GetDeviceConfiguration(long ipAddress)
            {
                string sprocName = ConfigurationBL.ReadSproc("ReadDeviceConfiguration");
                return db.ExecuteQuery<MM>("exec {0} @IPAddressNumber = {1}", sprocName, ipAddress).FirstOrDefault();
            }

Thanks, Justin
