Retry Interval
Specify in this field the number of seconds the system should wait before attempting to retry a failed event action or handler.
If this field is set to 0 (zero), the system does not wait at all between retries.
Take care when setting this value that you do not set it too low. Auto-retry is designed to take care of "self-correcting" legal failures, for example, network timeouts. This setting is meant to allow for pauses that allow whatever is having problems to correct itself. If you retry too quickly, whatever is having problems will most likely not have had a chance to correct itself.
