DNSSEC is not currently used on these servers.

There are no errors reported on the master server.

Master - named.conf

include "/etc/named.conf.local";

options {
        directory "/var/named";
        pid-file "/var/run/named/named.pid";
        };

zone "." {
        type hint;
        file "/etc/db.cache";
        };

key rndc-key {
        algorithm hmac-md5;
        secret "XXX";

controls {
        inet 127.0.0.1 port 953 allow { 127.0.0.1; } keys { rndc-key; };
        };

Configuration of the problem reverse zone:

zone "5.168.192.in-addr.arpa" {
        type master;
        file "/var/named/5.168.192.in-addr.arpa.hosts";
        allow-transfer {
                192.168.5.2;
                };
        allow-update {
                key rndc-key;
                };
        };

Slave Zone Configuration:

zone "5.168.192.in-addr.arpa" {
        type slave;
        masters {
                192.168.5.1;
                };
        file "/var/named/slaves/192.168.5.rev";
