Subject Re: log4j : How to avoid duplicate logmessages in a multithreaded application?
Date Wed, 30 Jan 2008 16:07:31 GMT
My guess is that log4j is being configured multiple times.  Each time
log4j is configured, the new configuration is added to the current
configuration.

How are you configuring log4j?
