IMHO, When you do logger.debug(connectionID + "-" + message); The string concatenation is evaluated before the call to the logger. You will find some litterature to this on google. HTH -- Olivier

Hello all, Iam not sure if there is really amemory leak in Log4jLogger. We use Mercury diagnosis tool to find the memory leak and the reports show all the string buffers being held up at 1. org.apache.log4j.Logger.debug 2. org.apache.log4j.Logger.info this is one of the call we make logger.debug(connectionID + "-" + message); logger is an instance of Log4j.Logger and connectionID,message are strings i know appending strings will internally create StrinBuffers but our memory reports show string buffers are never cleared which are areated during that call. any help is highly appreciated. Thanks, Naveen. Naveen It only takes a moment to be kind, but the results can be everlasting.!! __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo!
