We have a 7.4.3 multisite config. On September 3rd all scheduled jobs on all appservers stopped running. They'll run if you start them manually, but not otherwise. Where should I start looking for the solution to this? Fileserver/Database/appserver processes are all running, as far as I can see, normally.
Called this one in - fix seems to have been to delete schedules, redo them. Problem may have been related to an appserver that was trying to run everyone else's jobs, rebuilt it a while ago but somehow schedules were still broken.
Hopefully this might help someone else, thx...
