yes (and i'm aware of the existence of checkjob ;) it does, but as far
as i understood (and also given the reported values of eg MAXPS and not
MAXIPS) it does only show why the job can't be started, not why it is
not seen as idle.
i'm getting the impression that when a jobs violates a limit, it's
considered blocked and not idle by maui (as opposed to my understanding
of running/idle/blocked jobs)
The system will shutdown in 5 minutes.
