Frequent ndc restart needed

[MeltDown]

Hi!

I'm having a lot of trouble with my bind. Everything runs smoothly, except 
that every now and then I have to restart named. "Every now and then" can 
vary from twice a minute to once every two days. I have to restart named 
because at some point it will simply refuse to look up any address. It 
keeps accepting connections, it just returns a "DNS unknown" like message. 
It doesn't segfault or something.

Currently we (the people on my LAN) have a single nameserver, which serves 
both our internal and our external addresses. I know, it would be better to 
separate the internal from the external, and we'll do that soon, because 
we'll get us a second server.

Named also complains a lot about lame servers. Below is a snippet from the 
logs.

I hope you can help me. Restarting named is getting really annoying.

Greetz,
