Edit /etc/crontab and save. then reboot to make the new version take effect (alternatively use kill -HUP <PID>, where you can find the PID from the ps ux command to restart the crontab process ).
Logs
The log is kept in /var/log/messages. We believe this "rotated" (compressed, saved and deleted) automatically by syslog using /etc/logrotate.conf and /etc/syslog.conf, so memory is not eventually exhausted.
