[Mauiusers] multireq job not starting

Hello all.


We have a 33 nodes cluster composed of 9 4-cores and 24 8-cores nodes.

We have partitioned so that the 4-nodes are together and 8-nodes work in 
a separate queue.

One of our users sent yesterday a job for 128 tasks :
#PBS -l nodes=11:ppn=8+10:ppn=4

MAUI refused to run it, telling :
multi-req PBS jobs not allowed

I've found in torqueusers mailing list, that I should put :

ENABLEMULTIREQJOBS TRUE

into my maui.cfg file... now it is done, and the job does not start for 
another (unknown) reason... checkjob says :

checking job 6393

I wonder why I get this startdate...

My maui.cfg file contains (only lines changed from the default) :

BACKFILLPOLICY        FIRSTFIT

RESERVATIONPOLICY     CURRENTHIGHEST

NODEALLOCATIONPOLICY  CPULOAD

JOBNODEMATCHPOLICY EXACTNODE

RESOURCELIMITPOLICY     MEM:ALWAYS:SUSPEND

NODEACCESSPOLICY SHARED

ENABLEMULTIREQJOBS   TRUE


What do I miss ???
