I'm seeing the following in my sssd_DOMAIN.log:
Hi,
which version of SSSD are you using and how does your sssd.conf looks
like?

Do you see this all the time or only for a particular server?

found in list.

Are the messages in the middle anything to worry about? Doesn't sound
particularly good.
Some time ago the handling of the krb5info files for the Kerberos
locator plugin was enhanced by adding not only the IP address of the
current KDC to the file but the names of the next ones SSSD would
consider as well. With this other Kerberos clients have a chance to fall
back to other KDC if the one currently preferred by SSSD in not
available anymore and SSSD so far didn't notice this.
The error comes from this part of the code. So I think the worst case
would be that some KDC names in the krb5info file might be missing.
