The queued jobs run on a Windows service. If the window service is turned off for a server update, for example, the queued job will stop. When the service is turned on, the job will not restart automatically. Instead, the job will get a status of "Cancelled Service Restarted". You can then manually restart the job from the Queued Job main page.
You can receive an email informing of any job that has failed with a service restarted status.
Template must be selected on the "Queued Job Failed Service Restarted" email template assignment.
Email will be sent to the user who executed the job.
