According to the documentation, this means that the "node is not Idle or 
Running". What does pbsnodes -a say about the node states and job-node 
assignments? Is the information consistent with what diagnose -n shows?

Yes, it is as it should be.

By the way, showres run as a normal user may show fewer reservations than 
when you run it as administrator. However, had your job been rejected due 
to a standing reservation, the rejection reason would have been 
"Features", I think.
