Workflow Controllers have the option to stop a workflow instance and, it may happen that a workflow errors and then stops. In both cases the document will retain the current document status and it may go unnoticed by the workflow users to find out that a task simply has disappeared from their list. It would be great to have an ability to catch these documents either in a List or in a system workflow which then sends tasks or email notifications to dedicated members of staff - who are not necessarily workflow controllers
