[Mauiusers] insufficient idle procs available ?

'ncpus' still exists but only in 17 'old' jobs - ones that were submitted
before we made the 'unset' change. I guess I should wait until these will
end and re-test the system?

diagnose -n says for example, on node28 :

node28         Busy   0:4     2926:3950        1:1        3871:7641
1.00DEFAUL [NONE] DEF
2.19 002 [heavy_2:4][light_4:4][b_que   [DEFAULT]
[NONE]
WARNING:  node 'node28' has more processors utilized than dedicated (4 > 2)
-----                     ---   6:86   72602:98716      26:26
142420:212774

But this node is running 2 jobs which both does not have 'ncpus' settings if
I use qstat -f on them.

About the MEM requirement: do you mean to unset it to? other than that we
don't use any MEM requierment in our qsub script.
