[Mauiusers] job losing HOSTLIST

Encountered problems with hostlist disappearing / corrupting when 
submitting a job with
 > qsub -h -lnodes=2:ppn=2 -W 
x=HOSTLIST:node_003,node_003,node_004,node_004 xhpl.sh

PROBLEM 1: the hostlist got changed - checkjob shows hostlist= node_001 
and node_002 instead
and the job subsequently ran and  failed because these nodes do not have 
the hardware I requested.

PROBLEM 2: the entire hostlist is gone
The -h flag holds the job immediately after submit.  And I execute a 
checkjob immediately a checkjob
without otherwise altering the job.  Sometimes (although rarely) I got 
output which says the job lost
the following:
 - the Hostlist itself is missing
 - Flags:        RESTARTABLE (lost the HOSTLIST flag)

This happens once every 50-100 times I do a submit.  I have not been 
able to isolate a factor that
determistically triggers the error. 

I am running torque-1.1.0 and maui-3.2.6.  The verbose output of 
checkjob is enclosed towards the end.
Any help is much appreciated.
