I'm trying to restart a system process through cron and getting emailed the startup output of the process. I thought redirecting STDOUT and SDTERR to /dev/null would "silence" the output but alas, this has not work. How can I get cron to silently restart this service? crontab entry:

0 6 * * * service sympa stop &>/dev/null; service sympa start &> /dev/null

sample output from restart email:

 Stopping Sympa bounce manager bounced
   ...done.
 * Stopping Sympa task manager task_manager
   ...done.
 * Stopping Sympa mailing list archive manager archived
   ...done.
 * Stopping Sympa mailing list manager sympa
   ...done.
