[HTCondor-users] Getting SUSPEND_VANILLA evaluation error

[Andrey Kuznetsov <akuznet1@xxxxxxxx>]

I'm getting for all slots:

WARNING: EvalBool of SUSPEND_VANILLA resulted in ERROR or UNDEFINED

machine has in condor_config.local, among others:
WANT_SUSPEND = TRUE
DESKTOP = TRUE
SLOTS_CONNECTED_TO_CONSOLE = 1
SLOTS_CONNECTED_TO_KEYBOARD = 1

SUSPEND = ifThenElse($(DESKTOP),(($(KeyboardBusy) || $(ConsoleBusy))
&& ((SlotID <= $(SLOTS_CONNECTED_TO_CONSOLE)) || (SlotID <=
$(SLOTS_CONNECTED_TO_CONSOLE))) || ((CpuBusyTime > 2 * $(MINUTE)) &&
$(ActivationTimer) > 90)),FALSE)


In condor_config, the SUSPEND_VANILLA variable is commented out with #.
##  Only define vanilla versions of these if you want to make them
##  different from the above settings.
#SUSPEND_VANILLA  = ( $(KeyboardBusy) || \
#       ((CpuBusyTime > 2 * $(MINUTE)) && $(ActivationTimer) > 90) )
#CONTINUE_VANILLA = ( $(CPUIdle) && ($(ActivityTimer) > 10) \
#                     && (KeyboardIdle > $(ContinueIdleTime)) )
#PREEMPT_VANILLA  = ( ((Activity == "Suspended") && \
#                     ($(ActivityTimer) > $(MaxSuspendTime))) \
#                     || (SUSPEND_VANILLA && (WANT_SUSPEND == False)) )
#KILL_VANILLA    = false


I cannot find any other location of that variable, so why is it
throwing an error?
Condor version:
$CondorVersion: 8.0.3 Sep 19 2013 BuildID: 174914 $
$CondorPlatform: x86_64_RedHat6 $

Other machines on the cluster with the same OS, condor and config
files do not have the same problem.
