Hello all. 

My setup which has one primary and slave server was working fine since

All of sudden I started  getting the  problem of zones updates on slaves.
Which are not happening on time. it takes two hours to take the updates.  


Below logs for the reference, when I do required changes on masters, the
slave getting notified but without transferring the updated zone.


Jan  2 09:17:50 ns2 named[25563]: zone notify from serial 2019434243

Jan  2 09:24:45 ns2 named[25563]: zone notify from serial 2019434245: refresh in progress, refresh check

Jan  2 11:12:53 ns2 named[25563]: zone Transfer started.

Jan  2 11:12:53 ns2 named[25563]: zone transferred serial



Therefore, I wanted to know. How to force secondary/slave Name server to
update/refresh dns zones from primary DNS server? Just I  want a slave name
server to initiate a zone transfer immediately


Here is my /etc/named.conf, of the primary name server.



[root at ns1 ~]# head -60 /etc/named.conf

// named.conf


options {

        listen-on port 53 {;;;};

        listen-on-v6 port 53 { ::1; };

        directory       "/var/named";

        dump-file       "/var/named/data/cache_dump.db";

#       statistics-file "/var/named/ej.stats";

        memstatistics-file "/var/named/data/named_mem_stats.txt";

        masterfile-format text;

        version "Have a nice day!, Good Bye";

//      allow-query     { localhost; };

transfers-out 2000;

allow-transfer {;;;;};

#allow-notify {;;;; };

also-notify {;};

allow-query {;;;};
