Stale file handles when using log4j and tomcat?

[Fredrik Jonson <fr...@myrealbox.com>]

Hello,

When checking with lsof, I see that log4j seem to maintain file descriptors to log files even after I have stopped and even removed the webbapp which logs to that particular logfile.

I use log4j (1.2.7/9) and tomcat 4.1.31 on linux and java-1.4.2. Log4j is placed in the WEB-INF/lib directory, and isn't shared between apps, though several webbapps use log4j for logging.

Is there any trick to make log4j close logfiles when the webbapp is stopped?

I seem to recollect a previous discussion on a related topic on this list, but now I cant find it again.

Hi,

Have you tried using a ServletContextListener which calls
org.apache.log4j.LogManager.shutdown() in its contextDestroyed method?

This should allow log4j a chance to close any resources when you stop the
webapp context.

Regards

Andy
