After an update, nameserver became a mess

After I did an apt-get update, apt-get upgrade on perfect debian etch server, when I tried looking up my DNS records from network-tools.com:

mydomain.us is just a representation of my true domain.

It used to be running smoothly and displaying correct records, not it's displaying this:

Retrieving DNS records for mydomain.us...

what went wrong, and what did I do wrong?

 

I don't see no error till, here's the result when I restart bind9

Code:
