[Mauiusers] Maui QOS setting

I'm afraid I'm slow to get a handle on maui.

I have cluster PBS + Maui with several queues, and one of queues is  
limiting the number of jobs to it

For a job that's waiting to run on the "bigmemhigh" queue

checkjob JOBID


PE:  8.00  StartPriority:  81
cannot select job 24882 for partition DEFAULT (job 24882 violates  
active HARD MAXPROC limit of 32 for qos bigmemhigh  (R: 8, U: 32)


diagnose -Q

So I see that bigmemhigh has a MAXPROC=32 limit.  But I have not set  
that in the maui.cfg file, and the limit does not show up with the  
showconfig command or in the PBS parameters.

How do change this value?
