Unfortunately, I have been unable to submit new workflows to the CMS project since yesterday, and the job queues have now drained.
The cause is a change introduced in the development of the CMS work-flow management system. These changes are tested first on a development system before being moved to the production system. We currently use the development system to run CMS@Home, so the change is impacting us.
I'm trying to find out when a fix will be forthcoming, but until then set No New Tasks for CMS or switch to another project.
I'm sorry about this. I will let you know when I am able to submit jobs again.
