Komento Cron Job Failing

Hi,
We are having trouble with Komento cron job failing and causes a bog down in our mail queue.

Can you help me with this please?

Thank you,
Diana

Here is what our cpanel tech said:
*********************************
It appears that the following cron job is failing which is creating these error messages: /var/spool/cron/standup:*/5 * * * * /usr/bin/wget -O /dev/null "http://www.standupgirl.com/index.php?option=com_komento&task=cron";

Could you explain the function of this task to see if this may be related to the server? If not, I would recommend having your developer review this cron job to see what would be causing it to fail.
