In the Schedule Manager in SAS Management Console, the following pop-up error message appears:
Scheduling of "job-name" failed ('The interface to the scheduling server is not available. Contact SAS Technical Support.').
In the Trigger service log, messages that are similar to the following occur:

This problem occurs after a scheduled job runs, and that job is owned by a user who was previously deleted from the system.
This issue does not occur immediately after the user access is disabled, but it does occur after the SAS Job Flow Scheduler server reboots.
A workaround is either to unschedule all scheduled jobs that are owned by the invalid user or to delete the jobs that are owned by that user from the Task Scheduler on the operating system. Then reboot the server and re-initialize servers.
As a best practice, anytime that you need to remove a user from the system, ensure that you first delete any scheduled flows that are owned by that user.
