Timer start event

This event is used when a process is started on cyclic timer events either at specific points in time, after time spans or after timeouts.

If a workflow triggered by a timer start event fails before reaching the first asynchronous task, such as a user task, Collibra tries to restart it three times before stopping further attempts. Once the workflow is stopped, it no longer runs when the next timer event occurs, even if the underlying issue is resolved later.

To restart such a workflow, redeploy it.
