How do I properly Log4j, closing all Appenders and, therefore, files

Question

My servlet-based web-app sometimes fails to close Log4j log files when redeployed, leaking to file descriptor leakage and occassionally leading to servlet-contained dying from 'too many open files'.

I have a ContextListener, what should I put into its contextDestroyed() to tell log4j to shut down and release all resources?

Quick skim over javadocs revealed Hierachery class with shutdown() method. I have no idea on how to actually get the current Hierachery, and the javadoc states this class has no user-serviceable components inside :)

Answer 1

Try this:

org.apache.log4j.LogManager.shutdown();

However, the problem you are experiencing is strange and shouldn't be happening. What JVM, container, log4j version are you using?
