Yes, I've seen such values myself. PHP extension computes them by running getrusage() function twice and substracting the first result from the second. ATM I don't have a valid explanation except that these values are some kind of system artefact and quite probably I shouldn't even bother to report them in the log. If you have any ideas - let me know.
