[torqueusers] 2 Jobs per node limit in Maui?

Hi Nicola, 

Could you post a checkjob output of a job that is queued? It should have a reason for the job state, e.g. deferred, no resources available or something like that. There can be other resources than cores that inhibit execution, like memory, ncpus, sharing restrictions, etc.

Of course, the 'p s' and showconfig output as Gus said would be most helpful, just in case.
