If an error occurs during running of the Dependency Manager Deferred Process, after the normal number of retries, the system will move the work to batch processing instead. This protects against failures due to transaction timeouts and ensures that every avenue for processing the calculations has been tried.
Additionally, the status of the precedent change set in this case will be changed to be 'Deferred To Batch' to indicate that the deferred process was in error and a notification will be raised for the originator of the deferred process.
