[Condor-users] Upgrade problem

[Cliff Padgett <cwpadget@xxxxxxxx>]

Hi, I just upgraded a windows cluster from condor 6.6.11 to 6.7.19 
(trying to use the new groups abilities).  All the job on the cluster 
use a dedicated scheduler and are MPI.  Any Idea why jobs will not run 
now? They just constantly cycle from running to Idle.  The shadow log 
has the following errors, but I'm not sure what this means?
