Bug in Torque 1.2.0p6 ?

Hi.

We're running a 6-nodes cluster composed of bi-Opteron computers.

One of our nodes is currently running 3 jobs instead of 2, and we have a 
strange result when typing qstat :

                                                           Req'd

Job 7993 is marked as QUEUED, but has a processor reserved... the same 
processor as 7994 !

but it is actually RUNNING on the node :

The nodes file says :

callas01 np=2 opteron callas
callas02 np=2 opteron callas
callas03 np=2 opteron callas
callas04 np=2 opteron callas
callas05 np=2 opteron callas
callas06 np=2 opteron callas

and pbsnodes -a tells there are 2 jobs on the node :

# pbsnodes -a callas04
callas04
    state = job-exclusive
    np = 2
    properties = opteron,callas
    ntype = cluster
    jobs = 0/7447.ulmo.calcul, 1/7994.ulmo.math.u-bordeaux1.fr


What can be wrong ?
