yum update returns named errors...

[ActualizeAZ]

Fedora 7 Web Server running Plesk 8.3 control panel.

I recently ran yum update to get my server up to speed. It had been a while since I last ran it, so there were quite a few updates. I have had reports from remote users that they sometimes have DNS issues that come and go. I haven't been able to reproduce them myself, so I tallied it up to user error. However, after running yum update I returned a few errors with named, in regards to "caching-nameserver". What exactly is "caching-nameserver" and can anyone help me to understand these errors?

I'm not much of a webserver admin, and the DNS/bind stuff gets a little over my head. I am beginning to worry about my server and it's accessibility now that I have seen these errors.

Can anyone please help to understand these errors and their severity? What can I look into to fix it, is there any troubleshooting I can do?

Thanks so much for your help!

When I navigate to /var/named/ and run a ls -la this is the output I receive. Again, not much of a webserver admin, so I am having a bit of trouble deciphering this as well.
