Re: [HTCondor-users] dprintf_failure.SCHEDD & dprintf_failure.SHADOW

[Todd Tannenbaum <tannenba@xxxxxxxxxxx>]

Hi Chris,

Quick random guess:

Could it be a similar issue as this 
  https://lists.cs.wisc.edu/archive/htcondor-users/2017-March/msg00120.shtml
? 

In other words, is CONDOR_IDS=0.0 either in the config file or in the environment?  

regards,
Todd
