i think you just need to put another set of parenthesis around the test and use
of the UNDEFINED value, like this:

((TotalJobSuspendTime =!= UNDEFINED) && (TotalJobSuspendTime <= $(MaxSuspendTime)))
		
condor doesn't short-circuit the boolean evaluation, so it was still evaluating
the undefined attribute and getting ERROR.  the reason it works with the extra
parenthesis then is that:
  (FALSE && ERROR) == FALSE

i.e. the ERROR is squashed.


also, this actually changed in 6.7.14, and condor does short-circuit boolean
evaluation.
