Hi Milind, Thank you for your swift response. >>How many hours did you wait after the "start time" and decide to restart mgr ? We waited for ~3 days before restarting the mgr-service. There was one more instance where we waited for 2 hours and then re-started and in the third hour the schedule started working. Could you please guide us if we are doing anything wrong. Kindly let us know if any logs are required.
