SubjectRe: BIND hangs with 2.6.14

The strace is a little big (1.5GB), but sure, people can have it if they're
interested. OTOH, I just noticed that syslogd shows:

Oct 30 09:55:50 cirkus named[13364]: errno2result.c:109: unexpected error:
Oct 30 09:55:50 cirkus named[13364]: unable to convert errno to isc_result: 14: Bad address
Oct 30 09:55:50 cirkus named[13364]: UDP client handler shutting down due to fatal receive error: unexpected error

...and after that, everything seems to crash and burn. The related strace
call is:

[pid 13365] recvmsg(22, 0x561329b0, 0) = -1 EFAULT (Bad address)

Might this be a BIND bug instead? In that case, why doesn't it show up with
2.6.11.9? I've restarted BIND now without NPTL, to see if it might be
thread-related.

We're not going to change DNS server software anytime soon on our production
servers, but thanks for the tip :-)
