[wplug] Cron Daemon Message

[Gentgeen]

I'm not sure when it started, It was a while ago -- but once a day I get the following message 
from the Cron Daemon:

[--snip--]
Subject: Cron <root at linuxbox> test -e /usr/sbin/anacron || run-parts --report /etc/cron.daily
Date: Wed, 25 Feb 2004 06:30:40 -0500

run-parts: /etc/cron.daily/man-db exited with return code 2
[--end snip--]


This may sound like a silly question to some of you, but I'll ask anyway --
What does this mean?  (Running Debian Woody with 2.4.18 kernel)
