Please don't break up the format string. Start it on the second line and let it run as long as it needs to. Also you will find that it is improperly spaced as it is. It makes it easier to grep the source to find the source of a message. The coding style has an explicit exception for such long lines for this reason.
Also, please don't put .'s on the end of log messages. It serves no purpose and just adds to the log, the binary size and the source size. There are quite a few of these.
