Issue
This occurs on 2019.3 and only appears if there is a Schedule with a Next Run time between 12-2 AM on 11/3 for the US and on 10/29 for Europe. This is due to the time change, and the Gallery is not able to determine the time zone the Workflow should run in.
Other symptoms which customer may report or describe: scheduled jobs are active/queued but not running.
There are two errors that can appear. The below will show in the Service Log soon after service start-up.
ServiceScheduler_DoWork_StdError: Fatal top-level error
The following error will show when attempting to disable an affected Schedule.
- Schedules may show a Next Run date and time equal to the Last Run date and time, which may be in the past.
Environment
- Alteryx Server and Alteryx Designer with Automation
- Version 2019.3
Cause
This is caused by the Time Zone functionality not being able to recognize what time zone the Schedule is set for since the time it is scheduled for will 'repeat' with the end of Daylight Savings. It is recommended not to schedule anything for this time to avoid this issue.
Resolution
Now that the time has changed, it should only be necessary to Restart AlteryxService.
If that does not resolve the issue then:
- Delete the Schedules between 12 AM and 2 AM on the date of the time change (11/3 for NA and 10/29 for Europe)
- Restart AlteryxService
