Greetings, I have edited my /etc/org.ops4j.pax.logging.cfg file to the following, to allow each bundle to create a separate log file.  Unfortunately, the max file size and log indexing seems to not work when using the sift appender.  I will attach the config file, but currently all the logs only write to a single log and it can grow to an unrestricted size.

What am I doing wrong that prevents the log files from being indexed and rolling over?
