Resolution

Every event in ESP is scanned only when it is scheduled. At that time all statements are read and adjusted. And the statement NOSCHED is adjusted only at the time when the event is read,  usually when it is scheduled.

Here the explanation why the event is not scanned at NOSCHED time. When NOSCHED would be eg. every 1 minute and the SCHEDULE would be every 24 hours. the event would be scanned every minute to check out if it does matches with the SCHEDULE time at 24 hours. So it would cause big overhead for nothing.
