No experience, no. A rough hack would be to call WriterAppender::setWriter on a ConsoleAppender instance passing a custom Writer implementation that groks a mmap-ed file. I'm unconvinced this would work, however, given the behavior of the private ConsoleAppender::target member mentioned in ConsoleAppender::setTarget. A better version would be, I think, to create a new WriterAppender subclass doing what you want. Curiosity, turning off the buffering on FileAppender isn't close enough to what you want? - Rhys
