Bug 446848

Also occurs here. Only additional information I can give is there was a 
complaint about "too many timeouts resolving ... disabling EDNS the second 
before.

Previous bind release 9.5.0-23.b1.fc8 was OK. This problem is new with the 
latest one listed above.

Yes, I see similar errors in my logs about EDNS. I'm going to disable it to see
if that keeps it from crashing.

*** Bug 447228 has been marked as a duplicate of this bug. ***

Could someone attach backtrace, please? I'm not able to reproduce this problem.

1) install bind-debuginfo
2) make /var/named directory writable by named user (you should not see "the
working directory is not writable" message in log when named starts)
3) wait for crash
4) open core file in gdb ($gdb /usr/sbin/named <core_file>)
5) type "t a a bt" in gdb and attach output, please

Thanks

Thanks for it, would it be possible also attach named.conf, please?

core dump trace

I can e-mail you a named.conf directly if you need my input as well

It would be nice. Or you can attach it here and mark attachment as private. Thanks
