PowerDNS Bind backend with valid named.conf: Error in bind configuration '/etc/bind/named.conf' on line 1: syntax error

[Habbie]

Hello,

We have following issue with PDNS while we try pdn_control rediscover: Error in bind configuration '/etc/bind/named.conf' on line 1: syntax error

But config fine, we checked it via full pdns restart: Apr 6 14:16:10 ns2 pdns[15978]: [bindbackend] Done parsing domains, 2 rejected, 162772 new, 0 removed

After restart all works fine: pdns_control rediscover Ok Done parsing domains, 2 rejected, 0 new, 0 removed

Logs: Apr 6 10:10:12 ns2 pdns[29063]: Error parsing bind configuration: Error in bind configuration '/etc/bind/named.conf' on line 1: syntax error

Author: anon I'm sure about there are no changes in named.conf in this time.

Author: peter Can you please post a (small) named.conf that causes this problem?

Unable to reproduce with a typical named.conf.options. Can you supply this too?

Hello,

I thinks, it's powerdns bug. I have small error in named.conf (it synced every minute with central server) but it fixed very fastly (3 minutes after 17:45) but powerdns still show parsing error:

May be this related with extrimely big size of named.conf, it's 13 megabytes.

Hello,

I'm removed all includes and construct named.conf manually and commit it to powerdns after few checks (named-check).

After this I got error: Error in bind configuration '/etc/bind/named.conf' on line 682489: syntax error

Ok, I will check named.conf:

zone "avtozapchasti-101.info" {
    type master;
    file "/etc/bind/avtozapchasti-101.info";
};
zone "10-zapchasti.info" {
    type master;
    file "/etc/bind/10-zapchasti.info";
};
zone "zapchasti-avto777.info" {
    type master;
    file "/etc/bind/zapchasti-avto777.info";
};
zone "pornoigr.net" {
    type master;
    file "/etc/bind/pornoigr.net";
};
zone "new.isnano.ru" {
    type master;
    file "/etc/bind/new.isnano.ru";
};

As u can see, all configuration valid. I think, this issue related with very big named.conf size (13 Megabytes) and parser buffers overflow.
