I have been using Director since version 2.12 and I've had the same issue with all the versions up to 4.2, which is what I'm currently running. I setup scheduled jobs to go off at certain times and occasionally (About twice a month) the job for that day only will be deleted and therefore will not go off. If I have a job scheduled to go off every Monday at 5 AM until 2006, forever, or even for a few months, the job will get deleted for one day and the rest of the schedule will remain. I have also setup one time jobs and they also get deleted. I called IBM and opened a PMR. Has anyone seen this before? Any help would be greatly appreciated.
