[torqueusers] Max nodes seems to be 9 despite config

I have Torque managing 14 dual-processor nodes. The maximum number of
nodes for parallel jobs is set to 28 (the number of processors), both in
the queue config and server attributes. However, jobs requesting
anything more then 9 nodes are rejected with the error 'qsub: Job
exceeds queue resource limits'. Requesting either nodes=9:ppn=2 or just
nodes=9 works, but nodes=10 (regardless of ppn) or more does not. The
pbs_server log shows

12/28/2004 10:46:50;0080;PBS_Server;Req;req_reject;Reject reply
code=15036(Job exceeds queue resource limits), aux=0, type=1, from
mhuhtala at volvox.abo.fi

I am mystified. As far as I can see there should be nothing that limits
nodes to just 9. Is there something about queue config that I have not
understood? Config the queue in question and server attributes are below.
