I have a premise installation. I have a campaign workflow scheduled since last year. All of sudden since past week it is getting stuck at delivery activity without any errors.We do not have any approvals. Delivery is going into finished state and delivery file is getting created properly. However in same workflow downstream i have update query to update broadlogrcp table to update two fields. It is sticking at Delivery activity only and when manually i am running from the delivery task again it is completing successfully without any error. But on schedule basis it is not running till the end. Audit logs does not have any error information.
