Hm, I didn't think of that. How can I find out,
where all the disk access is coming from?

(A question I wanted to solve for a long time!)

No, the only open files are 
- the chroot directory
- the working directory
- the udp socket
- a local socket

So it looks like the disk accesses must come from something else.

rbldnsd is configured to only write stats every minute, but
no access logs.

I tried named once but it couldn't manage the zone files. I can't remember
if it just died or if it took insanely long to start up...
