Cron script dies silently if not redirect to /dev/null

Solution Unverified - Updated -


  • Script launched by crond is interrupted silently by the system
  • It appears that a script launched by /etc/crontab without redirection of stdout/stderr to /dev/null is interrupted by the system as soon as the output level exceeds a certain limit around 1kB.
  • There is nothing in /var/log/cron to indicate this interruption.
