CentOS 4.7, Kerberos 1.3.4

Hi All:

This is driving bonkers. A couple of weeks ago I started working on
implementing Kerberos. I got as far as getting the primary/master KDC
running on our CentOS development system before I got dragged off to
work on something a little more pressing. I finally got back to it
this week only to find that the krb5kdc service now fails to start.
A check of the log files shows it has been working right up until
the system was rebooted Sunday night. The reboot itself was not the
problem as there had been previous reboots after which krb5kdc was
able to restart.

Here are the log entries for that latest retry:

The "unrecognized local address family 17" message were occurring even
when it worked so I do not thing they are significant to this problem.

As far as I am aware I have not made any changes to the system that
should affect this.

I have done a ton of Google searches but I have not turned up anything
that seem to help. Any thoughts or suggestions would be greatly
appreciated.

TIA

Regards, Hugh
