> In the current implementation, it appears that messages scheduled for retry
> by the broker may be lost if the broker is not running at the time the job is
> scheduled to execute. If, for example, a message fails and is scheduled for
> retry at 1:30, with a 5 minute delay, the job will be scheduled to execute at
> 1:35. If the broker is running at 1:35, whether continuously or after a
> restart, the job will execute as expected and the message will arrive at the
> specified target destination. However, if the broker is shutdown before the
> scheduled time and then started again after that time, say at 1:40, the
> message appears to be discarded and is not sent. The same behavior appears
> to apply as well to messages sent originally with a delay.
> This may result in loss of a message that needed to be processed. While
> there may be scenarios where precise execution time of a job is critical
> (i.e. a job scheduled for 1:35 should not run at any time other than 1:35),
> it is also possible, and in the case of retries probably likely, that the job
> should execute regardless. Message loss is generally "bad" and it would
> likely be preferable that the retried message be sent at the scheduled time
> or the next available opportunity in the case of a broker that is not running
> at the scheduled time.
