Crontab is updated at every deplo

Hello

Every time I do a deploy for one of my instance the crontab is edited and this line is added

** ** ** ** * /home/ec2-user/aws-scripts-mon/mon-put-instance-data.pl --mem-util --mem-used --mem-avail

So I end up with a crontab with 20 lines like this one which is problematic.

It causes various problems, the main one is our instance's disk space is full after a dozen of deploy because of spool/mail/root and mails logs.

Any idea why is this occurring ?

Thank's
