I had installed bind-chroot from yum not long ago, and saw that there were errors in the daily logs from named. Under further investigation, I noticed a directory loop. The named files resided under /var/named, with the chroot being in /var/named/chroot. For whatever reason, /var/named/chroot/var/named just leads back to /var/named. ls -al doesn't show any link between the directories.

I'm not really the most linux savvy, so I don't really know what more information I can provide you all with. Please let me know if there is some other piece of information I can give you that would be helpful.
