Ceki, Anton, many thanks for your replies. I added an issue: http://jira.qos.ch/browse/LBSITE-14 Hello Syvalta, Anton, Anton's recommendation to invoke ((LoggerContext)LoggerFactory.getILoggerFactory()).shutdownAndReset() within a contextDestroyed method of a ServletContextListener is exactly right. His later mention of the Context Selector chapter in the logback manual is also relevant, but only if slf4j-api.jar and logback-classic.jar are shared between application (as he also mentioned). I think the problem you are facing merits an entry in the docs, at least in the FAQ. Syvalta, would you mind entering a bug report in http://jira.qos.ch on this subject? The contents of your email are sufficient for creating the entry. (If you do mind, please let me know and I'll take care of it.) -- View this message in context: http://www.nabble.com/log-files-locked-after-application-undeploy-tp17619508...
