I found this, in my logcheck email. Any ideas? Should I be worried? Or is it
just something that sometimes happens?

If you already have a root hints zone defined in named.conf
you need to update the address in the file it loads from.
The easiest way to create a new file is to run dig, check
the contents of the file it generates then move the file
into place.
dig ns . @a.root-servers.net > newfile
If you don't have any root zone defined they you will be
using the built-in hints. In this case you should create
a root hints zone if you don't have a root zone already
defined and you are using class IN (the default class).
dig ns . @a.root-servers.net > root-hints
zone "." {
type hint;
file "root-hints";
};
If you are not using views you do this at the options level.
If you are using views you need to define this zone in
each view of class IN.
BIND 9.3.5, BIND 9.4.2 (9.4.2rc2) and BIND 9.5.0 (9.5.0a7) will
have their built-in root hints updated to reflect this change.
If you wish to change the built in hints apply the attached
patch. In the top level directory run.
patch -p1 < l-root-servers.patch
make clean

Microsoft has single-handedly nullified Moore's Law.
Innate design flaws of Windows make a personal firewall, anti-virus
and anti-malware software mandatory. The resulting software arms race
has effectively flattened Moore's Law on hardware running Windows.
