Description Adrian Offerman 2013-04-03 19:53:42 UTC
Created attachment 731323 [details]
corrected sample file /usr/share/doc/bind-9.9.2/sample/etc/named.conf

Description of problem:

After a while CPU load of BIND named goes over 200% and stays there, while still serving answers to DNS queries.

Version-Release number of selected component (if applicable):

9.9.2-8.P1.fc18.x86_64

How reproducible:

Start it up, and just wait for a couple of hours, or one or two days :-)
Note: this was on a very lightly used system.
Restarting the daemon won't help; the daemon runs normal again for a while only after rebooting.

Additional info:

This problem appears to be triggered by a missing statement:
  managed-keys-directory "dynamic";
in the /etc/named.conf file.
This problem was already reported in bug #709205 for BIND named 9.7.4 on FC14 here:
  https://bugzilla.redhat.com/show_bug.cgi?id=709205

Yes, the managed-keys-directory statement is there in the basic named.conf that is installed with the package. However, it is missing in the template configuration file /usr/share/doc/bind-9.8.2/sample/etc/named.conf that a lot of people might be using.

Attached a corrected sample file (added the DLV key path too).
