Timer Jobs don't run after changing the schedule

I created a custom timer job. It used to run fine during development an initial testing when I using SPMinutSchedule for scheduling it every minute of 5 minutes. The intention is to run it once a day in production. So, I changed the 开发者_如何学运维schedule using SPDailySchedule and it stopped running. I kind of fixed it by clearing the cache of the server each time I change the schedule.

I deploy the job using a feature with Web Application scope.

Am I missing something here?
