  <p>At first we though this was an error allocating the desired resources (VM's) for the job, but in fact the job ran fine and it was able to scale up as needed. It seems to be when trying to retrieve the job status is the problem.</p>
  
  <p>Interestingly, each time the error was thrown in the application (there were multiple reported while the job ran), the developer console would also bork with this:</p>

  <p>The job id is: <strong>2015-05-04_20_49_53-2521857061976321751</strong></p>
  
  <p>What is this warning/error related to?</p>
