[jboss-jira] [JBoss JIRA] (AS7-6255) Memory leak caused by endless piling up of delete-on-exit hooks for JMX authentication challenges

Taras Tielkes created AS7-6255: ---------------------------------- Summary: Memory leak caused by endless piling up of delete-on-exit hooks for JMX authentication challenges Key: AS7-6255 URL: https://issues.jboss.org/browse/AS7-6255 Project: Application Server 7 Issue Type: Bug Components: JMX Affects Versions: 7.1.1.Final Reporter: Taras Tielkes Assignee: Stuart Douglas We're running 7.1.1, with a patch applied for REMJMX-45 to limit the worst leaks coming from the JMX subsystem. However, even with this patch applied we can only survive for a few days in a production-like scenario. Inspection of the out-of-memory heap dumps shows a large accumulation of entries inside {{java.io.DeleteOnExitHook}}, all having values like "{{C:\jars\jboss-as-7.1.1.Final\standalone\tmp\auth\challenge-4303257}}". Given sufficient JMX connections made to a running instance of 7.1.1, this will at some point exhaust the JVM heap. Typically the paths will be longer than the example above, accelerating the process. -- This message is automatically generated by JIRA.
