This option specifies the time the Task Engine waits until attempting 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 waits for the specified period of time before attempting to re-deliver the completion event so business process execution can proceed. To change the number of re-delivery attempts, see Completed Task Re-Delivery Count.

The default time is 60000 milliseconds.
