[Samba] Hostname and kerberos

In samba 4 log I get the following message:

I changed the hostname in /etc/sysconfig/network to name of realm, but it
didn't help. I use samba 4, centos 6.3. Please help me. Pavel

Don't worry about this.  I'll need to change the log level of the
message, it isn't important, just a status message.

This is more odd, but is anything actually wrong?

Perhaps you have IPv6 half-enabled in some way?

[Samba] segfault Re: Errors, errors, errors in log

Jeremy,

This backtrace looks like it might be something to do with your recent
struct DIR work.  The revision 5727bfa is from master after the work you
did for Ceph in the VFS.

????????? ????????,

This is the first time we have seen this particular crash.  Essentially
all such INTERNAL ERROR messages are bugs in Samba that we fix as soon
as we can.  If you can give more details of your specific OS and
configuration, Jeremy will be able to help you.

Could be:

Pavel, please retest with 251767cde9a146d8122d76e257ab232c05ad452a.

I think David nailed it. I think this is likely to be
the bug I just fixed with the earlier patch.

[Samba] segfault Re: Errors, errors, errors in log

Thank you all! But can you say, what? I should do? We have samba 4 on our server
and people use it. It already has some data (users,group etc).
Please, can you explain what I should do now step by step?

Running make install should not overwrite any runtime state. That said,
backups are always encouraged.

After updating your source tree, you can check to see whether the
proposed fix is included by running git log.

Please see:
