If you're using crontab, make sure you've got the output environment variables SCHEDULE_* set as expected. This page has a useful explanation: http://www.mkssoftware.com/docs/man1/crontab.1.asp

If you're using crontab, the right way is to pipe your output stream to a file to review later. Otherwise, crontab will try to email each output to you using sendmail for your review.
