We've been on 11D for a while, and while it's been an improvement over 9.x one annoying thing is disappearing jobs.
We've got some full backup jobs scheduled to go every weekday, for example the Tuesday job is set to run every Tuesday of the month at 11:00.
Once in a while (seems random) some of these jobs just disappear from the schedule, and we have to re-schedule them. Luckily the jobs are still in job setup, so we don't have to re-create them.
I just ran Liveupdate, and we're now at 7170, so maybe that will help.
Has anyone else run into this? I did see one thread when I searched, but for some reason I couldn't reply to it.
