How do you stop named from creating named.run files?

Our DNS servers are piling up massive 2-3gb named.run files and was wondering how to disable named from creating/reporting to these files. I don't need the report and would rather save on the read writes. I found this old thread but it doesn't say where to disable it.

  Hi @WebHostPro, The following entry will exist in the /etc/named.conf file when debug logging is enabled: channel default_debug { file "data/named.run"; severity dynamic; }; };
  To disable debug logging, update this entry to: channel default_debug { null; }; };
  Then, restart the service using the following command: /scripts/restartsrv_named
  Let me know if you don't see this entry in your /etc/named.conf file. Note you will need to manually remove the existing named.run log file to free up the space. Thank you.

  Yeah, the named.conf file in the etc folder doesn't have that code. It just has a bunch of DNS zones and this: include "/etc/rndc.key"; controls { inet 127.0.0.1 allow { localhost; } keys { "rndc-key"; }; }; // // named.conf for Red Hat caching-nameserver // options { directory "/var/named"; dump-file "/var/named/data/cache_dump.db"; statistics-file "/var/named/data/named_stats.txt"; /* * If there is a firewall between you and nameservers you want * to talk to, you might need to uncomment the query-source * directive below. Previous versions of BIND always asked * questions using port 53, but BIND 8.1 uses an unprivileged * port by default. */ // query-source address * port 53; }; // // a caching only nameserver config //

  Hello @WebHostPro, You can also set the debugging level to "0" with the following commands: rndc notrace rndc reload /scripts/rebuilddnsconfig
  Can you let me know if that stops the addition of new entries to the named.run file on an affected system? If not, can you let me know the specific recent entries that appear in the named.run file? Thank you.

  I think that worked! I got some warnings, do they look like anything I should worry about? WARNING: key file (/etc/rndc.key) exists, but using default configuration file (/etc/rndc.conf) root@1234 [/var/named/data]# rndc reload WARNING: key file (/etc/rndc.key) exists, but using default configuration file (/etc/rndc.conf) server reload successful and This looks good! [/var/named/data]# /scripts/rebuilddnsconfig Waiting for "named"named" Service Status named (/usr/sbin/named -u named) is running as named with PID 11782 (pid file+/proc check method). Startup Log Starting named: [ OK ] named restarted successfully.

  Hello, You can safely ignore that warning message. It's due to the existence of the /etc/rndc.conf file, which isn't needed because the entries it uses are already defined in the /etc/named.conf file. Internal case CPANEL-20503 will address this false warning message in cPanel & WHM version 74. Thank you.

  Hi cPanelMichael, It looks like you missed }; in the below code, could you please confirm? To disable debug logging, update this entry to: channel default_debug { null; };

  Hello @abdelhost77, I updated the previous post to reflect the syntax correction you noted. Thanks!
