Warning:
Can be really server intensive on huge boards!
Code:
<cronentries>
<cron varname="gxboxlive" active="1" loglevel="1">
<filename>./includes/cron/miner.gxboxlive.php</filename>
<scheduling weekday="-1" day="-1" hour="-1" minute="-1" />
</cron>
</cronentries>
The cron is set up to run EVERY minute 24/7. I recommend going into your scheduled tasks and change it to run every Monday or everyday at a specific time.
