howto find errors in log?

[christiantdk at my-deja.com]

(I tried to post before, but it seems the server didnt agree with me..!)

We run DNS servers with several thousands of domains, to find errors
I've made a script which goes through the log files and searches for:

Xfer-log
1. "Err/TO getting serial# for"

default
2. "contains our address"
3. "rejected due to errors"
4. "syntax error near"
5. "could not open"

As I understand, it means:
1. Slave server was unable to do a AXFR.
2. The server is authoritative but doesnt know.
3. The zone had errors?
4. Syntax error in named.conf (can it also be a zone file?)
5. File specified in named.conf could not be opened. Is it only master
servers?


The question is if there are any other errors which can be logged and
mean that our servers are misconfigured?

I've seen "sysquery: findns error NXDOMAIN" a couple of times, as I
understand, it means that the server receives a recursive query for a
zone delegated to a server which doesnt know? As it could be any
domain, it shouldnt matter to me?

As we have a lot of people making changes to the zones all the time, we
have thought about doing a web-interface to Bind, which make it
impossible to do any syntax errors and other stuff.. We thought about
loading all the zones into a database and then periodically dump the
contents to the disk.. Anyone know if software to do it exists? Anyone
have some thoughts on the subject?
