  # To increase performance of job execution and the web interface, you

  # documentation:
  # https://docs.galaxyproject.org/en/master/admin/scaling.html  By

  # job running capabilities can be configured through the job
  # configuration file.

  # When jobs fail due to job runner problems, Galaxy can be configured

  # control of this is available with resubmit declarations in
  # job_conf.xml. For simple deployments of Galaxy though, the following
  # attribute can define resubmission conditions for all job
  # destinations. If any job destination defines even one resubmission
  # condition explicitly in job_conf.xml - the condition described by
  # this option will not apply to that destination. For instance, the

  # time_since_queued < 300)' would retry up to two times jobs that
  # didn't fail due to detected memory or walltime limits but did fail
