DNS服务启动失败

如题!
我是在fedora14下yum安装的named.caching-namesercer,bind软件也安装了的，但是service named start 直接提示的启动失败，没有任何提示（这应该说明区域配置文件是正确的吧），我的named.conf文件如下

options {
listen-on port 53 { any; };
listen-on-v6 port 53 { ::1; };
directory "/var/named";
dump-file "/var/named/data/cache_dump.db";
statistics-file "/var/named/data/named_stats.txt";
memstatistics-file "/var/named/data/named_mem_stats.txt";
allow-query { any; };
recursion yes;

dnssec-enable yes;
dnssec-validation yes;
dnssec-lookaside auto;

/* Path to ISC DLV key */
bindkeys-file "/etc/named.iscdlv.key";

managed-keys-directory "/var/named/dynamic";
};

logging {
channel default_debug {
file "data/named.run";
severity dynamic;
};
};

zone "." IN {
type hint;
file "named.ca";
};
zone "test.com" IN {
type master ;
file "named.test.com" ;
};
include "/etc/named.rfc1912.zones";
include "/etc/named.root.key";
还有rndc：
[root@localhost named]# rndc stats
WARNING: key file (/etc/rndc.key) exists, but using default configuration file (/etc/rndc.conf)
rndc: no server specified and no default
请问大侠，怎么回事呢？也说说我改怎么排解错误，排解错误的方法等。。小弟万分感谢
