[Mauiusers] MAXPROC issues

Hi All,

I am trying to ensure that users have a soft limit of 16 but a hard 
limit of 64 which is the maximum number of processors in our system.  I 
have a single user in the queue and all of his jobs show that he 
violates the active SOFT MAXPROC limit of 16.  Shouldn't maui see that 
there is no one else in the queue and launch the rest of his jobs, at 
least until another users job is submitted at which time it would wait 
until it could launch that users job?

I have defined the following maui configuration. What am I doing wrong?

# maui.cfg 3.2.6p20

# PBS Server for this node
SERVERHOST            headnode

# primary admin must be first in list
# ADMIN1 can do anything
# ADMIN3 read-only access to everything
ADMIN1                root admin1
ADMIN3                ALL
