Our core server is running 8.7 at the moment with about 7000 entries (workstations and servers).
Scheduled tasks never really posed a problem except for some rare occassions where we experiences stalled jobs (restarting the Scheduler service was enough to troubleshoot this).
Since last week, we're not able to start or "send" any scheduled task anymore > any workstation that's been drag 'n' dropped to the scheduled task will receive a status 'active' when the job is started. We've already restarted all LANDesk services and even restarted the server. Still no luck...
Had a look under c$\program files\landesk\managementsuite\log but there's also one mention of the workstation involved in the PatchCore.log (scheduledTaskhandler_???.log is not updated)...
