Zimbra Convertd Process "Find and Remove"

[det]

Hi,

I noticed the convertd process in zimbra is taking much resource doing the ff. commands.

find /opt/zimbra/convertd/convert -mmin +20 -type f -exec rm -f {} ;

I wonder on what conditions is this executed? I didn't see such in cron. is it safe to kill these processes? there are a couple of them.



thanks,
det
