Dear all,
I have a problem with standing reservations claiming too many nodes after some 
time. 

I have 12 compute nodes with 8 processors each. Eight nodes have feature 
'blade' defined, the remaining four don't. I want to make 2 daily standing 
reservations, reserving 4 complete 'blade' nodes, so 32 processors in total. 
This is my config:

  SRCFG[fc00]           STARTTIME=03:20:00 ENDTIME=06:45:00
  SRCFG[fc00]           QOSLIST=fc
  SRCFG[fc00]           TASKCOUNT=4 RESOURCES=PROCS:-1 NODEFEATURES=blade

  SRCFG[fc12]           STARTTIME=15:20:00 ENDTIME=17:45:00
  SRCFG[fc12]           QOSLIST=fc
  SRCFG[fc12]           TASKCOUNT=4 RESOURCES=PROCS:-1 NODEFEATURES=blade

So task count 4 and number of processors -1 (I have tried 8 as well).

When restarting Maui it looks okay, e.g. showres will show that 4 nodes and 32 
processors have been reserved:

  ReservationID       Type S       Start         End    Duration    N/P    
StartTime
  fc00.1.0            User -    11:37:33    15:02:33     3:25:00    4/32   Thu 
Mar 25 03:20:00
  fc12.0.0            User -   -00:00:09     2:02:33     2:02:42    4/32   Wed 
Mar 24 15:42:18
  fc12.1.0            User -    23:37:33  1:02:02:33     2:25:00    4/32   Thu 
Mar 25 15:20:00

It stays okay for about a day, then suddenly the (renewed) reservations will 
happily start claiming more nodes and processors then necessary, also nodes 
that don't have the 'blade' attribute. It may for example reserve 10 nodes and 
80 processors.

This looks like a bug..
