It looks like it is something wrt to skipping scheduled jobs so I will do some investigation. It is skipping jobs as per seta rules, but generating this exception.

Alin, you are welcome to keep troubleshooting this if you want.  You mentioned in the meeting today that you were looking at it. If not, I can debug once I finish some other projects.

Okay, I'll take a look at this when I get the chance and update the bug if I find something.

probably not going to fix this since buildbot is on it's way out the door
