Hmm. I tweaked the following with my reasoning as comments:

# I'd rather a job sit in the idle queue for days than get blocked
DEFERCOUNT 1000000
# re-evaluate blocked jobs once a minute
DEFERTIME 0:01:00

# prefer that time in the queue is a major factor
QUEUETIMEWEIGHT[0]      10

# look at the prior hour for FairShare factors with steep forgetfulness
FSPOLICY                DEDICATEDPS
FSDEPTH                 6
FSINTERVAL              0:10:00
FSDECAY                 0.50
FSUSERWEIGHT            1

# allow up to 1000 days of wall-clock time
USERCFG[DEFAULT]        MAX.WCLIMIT=86400000
# allow a user 128 processes, backfill upto 256
USERCFG[DEFAULT]        MAXPROC=128,256
# allow a user to use up to 256 nodes (which is more than we have??)
USERCFG[DEFAULT]        MAXNODE=256
# allow even more allocation for the idle queue to prevent jobs getting 
blocked
USERCFG[DEFAULT]        MAXIPROC=2048 MAXIJOB=256 MAXINODE=256
# allow around 50% of the queue to any user before penalizing
USERCFG[DEFAULT]        FSTARGET=50


Am I misunderstanding something?
