Apologies for the late response. All forum watch notifications were disabled in the forum migration and we were not made aware.
The reason for this is that the jobs have to be run with a run profile and run label in order to ensure the various jobs that share processes do not lock each other out. This is in the documentation. The Director UI is for design and jobs should not be started from here except by scheduling. Please run the jobs with the right run profile and run label from the Server Console UI following the CDS documentation.
