[Mauiusers] WARNING: node 'node2' has more processors utilized than dedicated (4 > 3)

Hi everybody,

I've a question about how Maui derives the number of processors 
currently utilized. It seems that from our 32 processors only around 22 
are active at the same time. All jobs in the queue are 1 processor jobs.

When we run diagnose -n we get the warning
   WARNING:  node 'node2' has more processors utilized than dedicated (4 
 > 3)
for more than 1 node (full output below). If we login on that node and 
check the currently in-use resources with 'top', only 2 processes are 
running, both using 1 processor and around a quarter of the memory capacity.

We already tried to set the NODEAVAILABILITYPOLICY to DEDICATED:PROC and 
rebooted Maui, but that does not solve the problem. We also searched for 
the warning in this mailinglist, but didn't find an answer so far. Can 
somebody help us.

Kind regards,
