Named has been working fine for months on Fedora core 14 with updates current.
a few days ago it stopped working. I tried a service named restart and received the error message:
stopping named: umount: /var/named/chroot/var/named: device is busy
I tried using kill process, which did not work. However if I use kill 9 <named process>, followed by service named stop, I can then restart the service and it works for a number of hours (less than a day), then stops again and produces the error message above when I try to restart it.
I can get it working again using the procedure above, but only temporarily.
Anyone have any ideas what might fix this issue permanently?
I have attached some samples of named errors found in messages log. Also, I have many gigs of spare disk space on all mounted drives.

The number of errors like this are significantly high. In one day there are probably over 100. These are occuring while named is working and do not seem to cause named to stop. I found nothing in logs to indicate why named stops.
Upon further checking, I discovered that my named.conf file does enable dnssec. dnssec-validation is yes also.
bind-keys file and managed-keys-directory are also specified.

also, recursion is set to yes, if that matters.
Well the errors your posting have to do with dnssec. You might want to take the dnssec options out of named.conf and see if that resolves your issues. If it does and you want to use dnssec, then you can start AFTER you make sure bind is running correctly without it.
