Actually, these lines in your configuration file are defining this behaviour. 
If the Patch.Ticket logger decides to fire, it will not only forward it to 
the message to the attached appender, but also have it bubble up the 
hierarchy, where it will be forwarded to all appenders on the way up (to the 
appender attached to the "Patch" logger in this case).

There's an explanation of this as well as a solution on

    <A HREF="http://www.perl.com/pub/a/2002/09/11/log4perl.html?page=3">http://www.perl.com/pub/a/2002/09/11/log4perl.html?page=3</A>

in the "Beginner's Pitfalls" section. 

And, I might add, the trick Kevin showed you with

    log4perl.oneMessagePerAppender = 1

would probably cause an outrage with the log4j folks. But it is elegant, 
nevertheless :).

Let me know if this answers your question.
