[ http://jira.qos.ch/browse/LBCLASSIC-33?page=com.atlassian.jira.plugin.system... ] Joern Huxhorn commented on LBCLASSIC-33: ---------------------------------------- I just checked this with a simple hello-world-webapp using tomcat 6.0.18. With <jmxConfigurator/> contained in logback.xml the classloader of the webapp will never be garbage-collected on re- or undeploy. All classes of the webapp remain in the heap dump. If I remove <jmxConfigurator/> the webapp is unloaded properly. This is quite bad...

unregistering in the jmx plugin -------------------------------

Key: LBCLASSIC-33 URL: http://jira.qos.ch/browse/LBCLASSIC-33 Project: logback-classic Issue Type: Bug Components: Other Affects Versions: unspecified Environment: Operating System: All Platform: All Reporter: Hontvári József Assignee: Logback dev list

I started using the JMX plugin of login, and I wondered how should I shut it down when a web application is restarted. I haven't found a function which unregisters the Configurator MBean. This object holds a reference (through ContextAwareBase) to a Context. I am afraid that not unregistering it causes a memory leak when a web application is restarted. There should be a way to shutdown the JMX plugin. Or more generally an API to shut down the Logback system in its entirety: flush buffers, close files etc. It must be decided what to do if a log request arrives when or after logback is shutting down.
