This option specifies the number of times the Task Engine attempts to re-deliver a task completion event to the Integration Server that hosts the Process Engine. For example, when a transport failure occurs between Task Engine and Integration Server (Integration Server is off-line or there are network problems) and a task is completed, the attempt to deliver the completion event to Integration Server fails. The Task Engine attempts to re-deliver the completion event until the specified number of attempts is reached. If the Task Engine is unable to deliver the completion event after the specified number of attempts, it places the task into an error state with an appropriate error code. When connectivity between the Task Engine and Integration Server is restored, you can re-submit the task completion event by manually changing the task status back to Active and then to Completed. To change the interval between re-delivery attempts, see Completed Task Re-Delivery Interval.

The default value is 30.
