[torqueusers] queue to node mapping is wrong when use '-l procs' option

 I failed to test queue to node mapping feature of torque/maui system, I
use torque 2.5.8 and maui 3.2.6p21. the simple job script contains a procs

#PBS -N simple-job
#PBS -l procs=3
#PBS -q fluent
#PBS -d /opt/share/job
sleep 30

The 'fluent' queue is mapped to a node 'cnode01' with 4 processors, the
setting is shown below:

# Create and define queue batch
create queue batch
set queue batch queue_type = Execution
set queue batch resources_default.nodes = 1
set queue batch resources_default.walltime = 01:00:00
set queue batch enabled = True
set queue batch started = True
# Create and define queue fluent
create queue fluent
set queue fluent queue_type = Execution
set queue fluent acl_host_enable = False
set queue fluent acl_hosts = cnode01
set queue fluent enabled = True
set queue fluent started = True
# Set server attributes.
set server scheduling = True
set server acl_hosts = snode01
set server acl_roots = root@*
set server managers = root at snode01
set server operators = root at snode01
set server default_queue = batch
set server log_events = 511
set server mail_from = adm
set server scheduler_iteration = 600
set server node_check_rate = 150
set server tcp_timeout = 6
set server mom_job_sync = True
set server keep_completed = 300
set server auto_node_np = True
set server next_job_number = 94
set server display_job_server_suffix = False

The job should use a single node 'cnode01' , while the allocated node
contains another node. see part of 'qstat -f' output:

    exec_host = snode01/1+snode01/0+cnode01/0
    Resource_List.neednodes = cnode01
    Resource_List.procs = 3

Can anyone give me some suggestion, it'll be greatly appreciated.
