No one on the Apple Support Discussion forums seems to know what this message means, so I wondered if any one here might... configd: FIXME: IOUnserialize has detected a string that is not valid UTF-8, "�SMB012". The above message started appearing in System.log on Jan 8 and repeats every 30 seconds! As you can imagine, this line appears in the log literately thousands of times. Anyone got any ideas? I assume it's network related and the complaint relates to the � character.
