I've been told that the problem has already been addressed in an internal build but,
it will be about 1 month before we can expect to see this fix applied in our version.
Some further info: I have the same entries, with the log file beginning at the time the computer woke up from hibernation. In other words, the log file seems to be started from scratch each day.
Mine had some extra different lines:
