As far as I could see at the time, the schedd was only loaded moderately, but 
the same user had more jobs in the queue but all of which had memory 
requirements beyond the ones for that machine. Cold that be a reason - I guess 
I could try to cross check that claim as well - so for now this is just a 
guess.
