BIND 9.2 "named" stop randomly

[blacklow]

Hi All
i'm using Bind 9.2 On Centos 4.4 As a DNS server for small
4 computers LAN (Win Boxs as well).
The named environment is not Chrooted.
lately i'v noticed that the named process stoped by itself
when I ran $ service named status
i get: " connect failed: connection refused " error.
running $ service named start
will get things up and running again but, this will last until the next time named will stop without any notice.



here is my named.conf file:


==========================================================
// Default named.conf generated by install of bind-9.2.4-//16.EL4

options {
directory "/var/named";
dump-file "/var/named/data/cache_dump.db";
statistics-file "/var/named/data/named_stats.txt";
allow-transfer { 192.168.1.0/24; };
version "example.com have some security measure";
allow-query { 192.168.X.X/24; localhost; };
// query-source address 192.168.X.X ;
// query-source address 192.168.1.0/24 port 53;
// forwards { 192.168.1.X }
//forward only;
// };

};
zone "." IN {
type hint;
file "named.ca";
};

zone "example.com" IN {
allow-query { any; };
type master;
file "example.com.zone";

};
logging {
category lame-servers { null; };

};

include "/etc/rndc.key";
===========================================================

i have leveled up the loggin mode using $ rndc strace
but i got nothing i can work with.

What am i missing ??
