[ http://jira.qos.ch/browse/LBCLASSIC-183?page=com.atlassian.jira.plugin.syste... ] Jose Guerra commented on LBCLASSIC-183: --------------------------------------- Hi I got a similar problem with logback in a webapp deployed on Tomcat 6.0.24 with Linux. I am using logback 0.9.17. It looks like the same issue. 11:35:25.666 [http-8080-2] WARN ROOT - Stopping logger context tracking Feb 11, 2010 11:35:25 AM org.apache.catalina.loader.WebappClassLoader clearThreadLocalMap SEVERE: A web application created a ThreadLocal with key of type [null] (value [ch.qos.logback.core.UnsynchronizedAppenderBase$1@57f389]) and a value of type [java.lang .Boolean] (value [false]) but failed to remove it when the web application was stopped. To prevent a memory leak, the ThreadLocal has been forcibly removed. Feb 11, 2010 11:35:25 AM org.apache.catalina.loader.WebappClassLoader clearThreadLocalMap SEVERE: A web application created a ThreadLocal with key of type [org.slf4j.impl.CopyOnInheritThreadLocal] (value [org.slf4j.impl.CopyOnInheritThreadLocal@35b5e8]) and a value of type [null] (value [null]) but failed to remove it when the web application was stopped. To prevent a memory leak, the ThreadLocal has been forcibly removed. Is there any workaround for this? Thanks
Tomcat reports SEVERE ThreadLocal issues upon shutdown ------------------------------------------------------
Key: LBCLASSIC-183 URL: http://jira.qos.ch/browse/LBCLASSIC-183 Project: logback-classic Issue Type: Bug Affects Versions: 0.9.18 Environment: Tomcat 6.0.24, JDK 6, Windows or Solaris Reporter: Anthony Whitford Assignee: Ceki Gulcu
I have a webapp that uses Logback, deployed on a Tomcat instance. Upon shutdown, Tomcat reports this and doesn't completely shut down: SEVERE: A web application created a ThreadLocal with key of type [org.slf4j.impl.CopyOnInheritThreadLocal] (value [org.slf4j.impl.CopyOnInheritThreadLocal@1bb35 b]) and a value of type [null] (value [null]) but failed to remove it when the web application was stopped. To prevent a memory leak, the ThreadLocal has been forcibly removed. Feb 3, 2010 10:49:22 PM org.apache.catalina.loader.WebappClassLoader clearThreadLocalMap SEVERE: A web application created a ThreadLocal with key of type [null] (value [ch.qos.logback.core.UnsynchronizedAppenderBase$1@10e2558]) and a value of type [java.lang.Boolean] (value [false]) but failed to remove it when the web application was stopped. To prevent a memory leak, the ThreadLocal has been forcibly removed. Is LogBack leaking resources?
