This message is in the other log as well and I think this is ok.

Have you check if the keytab on the host with issue has the latest key
version?

To check the call 'klist -k' as root on the server and then call 'kvno
host/...' with the principal shown in the klist output. Both kvno
numbers should be the same. If they differ call ipa-getkeytab on the
server to get a fresh keytab. Please note that you have to call kdestory
and kinit on the client to remove the old now invalid ticket from the
client's credential cache.
