Hi Terry,

its a way to ensure, that the scheduler uses the latest data for
its scheduling decision. Every object has a version number. When
the scheduler generates updates for an object (example: job start),
it includes the version number into that order to inform the qmaster
about the basis of its decision.

Unfortunately, there is a bug in u3, which delays the delivery of update
events. Therefore, the scheduler is not working on the most recent
data, and the qmaster logs the error messages you have noticed.

This can cause:
- losing usage in the sharetree.
- trying to start a job twice
- ignoring job start orders

The likely hod of a delay grows with the size of the share tree.

Cheers,
Stephan
