Truckmate is currently experiencing a latency issue with PC*Miler Webservices that is currently impacting the ability for the Mileage Service to process jobs successfully. As a result, TruckMate Support is temporarily stopping all Mileage Services on your environment to ensure that no mileage jobs are lost. Once normal service is restored, we will automatically restart your Mileage Services and all jobs will catch up and process. Please do not attempt to restart your Mileage Service in the meantime as this will result in data loss.
