Running bind-9.5.0-23.b1.fc8 - my hourly reconfig cronjob seems to have tripped
up bind on me. Only once so far. I set perms on /var/named so I'll get a core
if it happens again. Logfile says:
Mar 4 06:15:01 borlaug named: received control channel command 'reconfig'
Mar 4 06:15:01 borlaug named: loading configuration from '/etc/named.conf'
Mar 4 06:15:01 borlaug named: reloading configuration succeeded

The server has ECC memory and didn't throw a check.
I'm reporting this here as ISC seems to not want bug reports about b1 now that
they're on b2.
b2 is in testing repository now (see
https://bugzilla.redhat.com/show_bug.cgi?id=400461#c27). Would it be possible
try it, please? From changelog it seems that some fix might be related to this
Thanks. I've installed b2 and will report here (n theory, with a core) if I see
another crash, though I don't know how to reproduce it.
bind-9.5.0-26.b3.fc8 has been pushed to the Fedora 8 testing repository. If problems still persist, please make note of it in this bug report.
If you want to test the update, you can install it with
su -c 'yum --enablerepo=updates-testing update bind'. You can provide feedback for this update here: http://admin.fedoraproject.org/updates/F8/FEDORA-2008-3402
Another segfault today using the version from testing, but without the debugging
info this time:
May 5 14:45:01 borlaug kernel: named: segfault at dededede eip 00170c23
esp b7f26010 error 5
I also boned the aforementioned permissions, so didn't get a core (doh!). I
think I've fixed them now:
#ls -ld /var/named
drwxrwxr-x 7 root named 4096 Mar 11 22:26 /var/named/
but would appreciate notice to the contrary.
I do a reconfig every */15, so the timestamps line up to suggest this is the
Yes, /var/named has to be writable by named user when you want core file.
Segfault written above is different problem than original one. Attach core file
when next segfault occurs, please. Thanks
This message is a reminder that Fedora 8 is nearing its end of life.
Approximately 30 (thirty) days from now Fedora will stop maintaining
and issuing updates for Fedora 8. It is Fedora's policy to close all
bug reports from releases that are no longer maintained. At that time
this bug will be closed as WONTFIX if it remains open with a Fedora
'version' of '8'.
Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version'
to a later Fedora version prior to Fedora 8's end of life.
Bug Reporter: Thank you for reporting this issue and we are sorry that
we may not be able to fix it before Fedora 8 is end of life. If you
would still like to see this bug fixed and are able to reproduce it
against a later version of Fedora please change the 'version' of this
bug to the applicable version. If you are unable to change the version,
please add a comment here and someone will do it for you.
Although we aim to fix as many bugs as possible during every release's
lifetime, sometimes those efforts are overtaken by events. Often a
more recent Fedora release includes newer upstream software that fixes
bugs or makes them obsolete.
The process we are following is described here:
AFAICT, this update:
Jul 10 05:34:43 Updated: bind-libs - 32:9.5.0-28.P1.fc8.i386
Jul 10 05:34:56 Updated: bind - 32:9.5.0-28.P1.fc8.i386
Jul 10 05:35:23 Updated: bind-utils - 32:9.5.0-28.P1.fc8.i386
Jul 10 05:35:29 Updated: bind-chroot - 32:9.5.0-28.P1.fc8.i386
solved the issue. At least it hasn't recurred since then. Note, I believe the updates are changing /var/named to 750,root:named which stops potentially useful cores from being written (needs to be 770). Not sure if that's another bug or design.

It is intentional to have /var/named non-writable by named user.
