Adrián López created JBREM-1340: ----------------------------------- Summary: Memory leak related to org.jboss.threads.JBossThreadFactory Key: JBREM-1340 URL: https://issues.jboss.org/browse/JBREM-1340 Project: JBoss Remoting Issue Type: Bug Components: jmx remoting Reporter: Adrián López We have a memory leak when using the jboss-cli-client JAR inside of Jolokia. Jolokia uses remoting to connect to the JMX of several JBoss servers. After running for some days, the Old Gen memory space reach 100%. A heap dump analyzed with Eclipse MAT returns: {code} One instance of "java.lang.ThreadGroup" loaded by "<system class loader>" occupies 377.517.248 (87,28%) bytes. The instance is referenced by org.jboss.threads.JBossThread @ 0xe0a81ef0 HTTP-11 , loaded by "org.jboss.modules.ModuleClassLoader @ 0xe04ffe20". The memory is accumulated in one instance of "java.lang.ThreadGroup[]" loaded by "<system class loader>". The stacktrace of this Thread is available. See stacktrace. Keywords java.lang.ThreadGroup[] org.jboss.modules.ModuleClassLoader @ 0xe04ffe20 java.lang.ThreadGroup {code} I have created also another [issue|https://issues.jboss.org/browse/JBTHR-72] to jboss-threads, but looks the problem is not there. Same for [Jolokia|https://github.com/rhuss/jolokia/issues/401] Thanks -- This message was sent by Atlassian Jira (v7.12.1#712002)
