[Mauiusers] Stacking jobs using Maui/Running on shared nodes

I'm using maui v. 3.3.1 with pbs/torque v.2.4.11 and it seems maui is
refusing to share different jobs on the same nodes (from maui.log):

10/12 12:13:59 INFO:     located resources for 64 tasks (76) in best
partition DEFAULT for job 1519 at time 00:00:00
10/12 12:13:59 ERROR:    invalid nodelist for job 1519:0 (inadequate
nodecount, 29 < 32)
10/12 12:13:59 WARNING:  cannot allocate tasks for job 1519 at 00:00:00

There are clearly enough processors (76) free for the job (which needs 64,
at 32 nodes/2 processors per node) and then maui decides that it can't start
despite having enough processors to do so. Where is the configuration for
allowing the stacking of jobs in maui?

My maui.cfg has:

BACKFILLPOLICY        FIRSTFIT
RESERVATIONPOLICY    CURRENTHIGHEST
RESERVATIONDEPTH = 20
NODEAVAILABILITYPOLICY UTILIZED
NODEACCESSPOLICY        SHARED

NODEALLOCATIONPOLICY  CPULOAD

#also has a line for each node:

NODECFG[node01] MAXJOB=2
...
etc

Any help would be greatly appreciated.

Thanks,
Matthew
