### Details

:::note
This event is defined in the **auto_scheduling** extension, so you need to activate the [auto_scheduling](guides/extensions-list.md#autoscheduling) plugin. Read the details in the [Auto Scheduling](guides/auto-scheduling.md) article. 
:::

Auto scheduling places tasks in repeated passes until the result stops changing. This event fires when the result keeps changing and the engine stops after a number of passes without reaching a stable state. In practice this points to an over-constrained project - for example, a set of constraints and dependencies that cannot all be satisfied at the same time.

The `result` parameter contains the details of the run:

- `iterations` - *number* - how many passes were performed.
- `converged` - *boolean* - `false` in this event.
- `conflicts` - *array* - the conflicts collected during scheduling (see [onAutoScheduleConflict](api/event/onautoscheduleconflict.md) for the conflict fields).
