Crash with bind 9.2.4

[Jim McNamara]

Hello all. I had a crash on my nameserver tonight, and I'm curious as
to what may have caused it. It is a Debian box, running bind 9.2.4.
Here are the relavant logs:

Aug 29 20:24:58.612 general: critical: socket.c:2204: fatal error:
Aug 29 20:24:58.612 general: critical: select() failed: Bad address
Aug 29 20:24:58.612 general: critical: exiting (due to fatal error in library)

And the query that I'm assuming caused the crash:

Aug 29 20:24:58.559 queries: info: client W.X.Y.Z#59258: query:
40.244.170.161.in-addr.arpa IN PTR

The server is split view, only allowing queries for non-authoritative
domains from client machines, and W.X.Y.Z that issued the PTR query is
part of the acl that can ask the server anything and get useful
responses. It is a mail server, and asks tons of PTR queries all the
time, previously without any problems.

Google had nothing for me when I searched with some of the crash logs.
If you want/need any additional info, I'd be glad to supply it.

Thanks,
Jim
