Howdy folx,

I've got a little problem with BIND8.
Situation:
I run a small internel network with some servers and clients and have a dsl line.
The internal network is 192.168.x.x and all names are resolved.
Upon entering internet names www.somesite.org it forwards the requests to the DNS of my ISP.
This works perfect and fast.
---- Were's the problem ?? ----

After a random amount of time > 30 minutes, it takes ages to resolve names.
Like if the cached requests are poisened...

Some details:

The local resolve.conf is empty.

Extract named.conf

Code:
options {
        directory "/var/named";
        query-source address * port 53;  
        forwarders {
                forwardIP1;
                ForwardIP2;
                };
        };

zone "." {
        type hint;
        file "root.hints";
};

zone "0.0.127.in-addr.arpa" {
        type master;
        file "zone/127.0.0";
};

zone "somedomain.com" {
        notify no;
        type master;
        file "zone/localzone.com";   
        };

zone "0.168.192.in-addr.arpa" {
        notify no;
        type master;
        file "zone/reversezone.rev";
        };

Anyone suggestions ?

I'm currently using Cron to restart the BIND daemon ever 6 hours.
