Hi
I think this is a known issue for UiPath. We have had the same problem a few times in our on-premise Orchestrator.
UiPath told us to look for jobs in the Quartz table which are in state Error:
SELECT * FROM [UIPATH].[quartz].[QRTZ_TRIGGERS] where JOB_GROUP = ‘ORCHESTRATOR_INTERNAL’
Then try to set them to state Waiting and then the numbers should be correct again.
If in doubt, then consult UiPath Support.
Best Regards,
Martin
