cron.php using 450MB+ memory

[phila82r]

Hi all, I was just wondering if your cron job was using a lot of memory?

Mine uses more than 450MB...
Time:         Sat Aug 17 02:50:06 2013 -0400
Account:      xxxxxxx
Resource:     Virtual Memory Size
Exceeded:     458 > 200 (MB)
Executable:   /usr/bin/php
Command Line: php -q /home/xxxxxxx/public_html/xxxxxxxx/cron.php
PID:          28312 (Parent PID:28309)
Killed:       No

Is there any way to lower the mem usage?
