[Mauiusers] Clarification on MAXPROC

Good Afternoon all,
Using maui 3.2.6p14 with Torque 2.0.0p8
Dual Processor boxes configured with np=2 in $PBSHOME/nodes
We are setting a limit on users to a maximum of 132 processors total
allocated at any given time using:
USERCFG[DEFAULT] MAXPROC=132 #66 nodes
What we are seeing is a user submits a 32 node / 64 proc job and that job is
allocated and running.
The user then submits a second job with the exact same requirements. The
second job is then placed in the Deferred state, with the following error
message from: checkjob -v <jobid>
cannot select job 112642 for partition DEFAULT (job 112642 violates active
HARD MAXPROC limit of 132 for user userA (R: 64, U: 128)
My question is first what is the (R: 64, U: 128) referencing?
R:64 ( 64 running PROCS for this user? )
U:128 ( NO IDEA ) it looks like exactly double allocated procs
My thought was that 2 jobs at 64 procs = 128 total processors which is
Less than the 132 procs set by MAXPROC.
Why is the job deferred? Even with not enough available nodes
189 of 198 Nodes Active (95.45%)
Shouldn't this job be in the IDLE section of showq and not blocked/deferred?
Thanks in advance for any help.
