A workflow has a scheduler and default error management. What happens if an error occurs during a run?

In Adobe Campaign Classic, a workflow is a single, persistent process. When an error occurs in an activity, the default error management behavior pauses the entire workflow instance. This paused, erroneous state is considered an active instance. The Scheduler activity is designed to trigger a workflow's execution, but it will not start a new instance if one is already running. Therefore, as long as the workflow remains in its failed state, the scheduler will not trigger subsequent runs at the next scheduled times. The workflow must be manually stopped and restarted to clear the error and resume the schedule.

A. The scheduler cannot start another run because the existing workflow instance is still active, albeit in a paused/error state.
C. There is no default 24-hour waiting period for error handling; this would require custom configuration.
D. A new run is not started. The original run is the one that is stopped at the activity where the error occurred.

1. Adobe Campaign Classic v7 Documentation, "Error management" section: "By default, a workflow in error is stopped. The task is abandoned and is not re-executed. The next executions of the workflow will not take place as long as the error is not repaired." This directly confirms that no new runs will be started by the scheduler.

2. Adobe Campaign Classic v7 Documentation, "Workflow properties" section, "Execution" subsection: "In case of an error, the workflow is paused and the activity that is being executed when the error occurred turns red. The administrator is notified and can resume the workflow execution once the error has been fixed." This explains the "paused" state of the workflow, which prevents the scheduler from initiating a new instance.
