Discussion

• Modeller jobs get killed
  • There is a worker pool of 10 or 20 workers.
  • If job goes over 3 hours it gets killed by a monitoring process.
  • There is no useful error logged. User just sees "job failed", and they are likely to try again.
  • Eric suggests maybe a 6 hour limit is better.
  • Do not yet have sessions save in-process modeller jobs.
  • Saving a session should warn that modeller jobs was not saved.
