 Yes.  In particular it means that the job will never match any machine. From: HTCondor-users [mailto:htcondor-users-bounces@xxxxxxxxxxx]
On Behalf Of Sunshine It works well, but one day it was down. And the job always is idle.  I use condor_q -analyze some jobs, sometimes i get error or some information. "Job ClassAd Requirements _expression_ evaluates to false", does it mean the job will never run? [gwei~]$ condor_q -analyze 6653.0 Error:  Could not fetch startd ads [gwei~] ...... [gwe~]$ condor_q -analyze 6653.0 -- Schedd: x.x.x.x: <x.x.x.x:59301?...
