[esb-issues] [JBoss JIRA] Closed: (JBESB-1796) Memory Leak in Content Based Router

Memory Leak in Content Based Router ----------------------------------- Key: JBESB-1796 URL: http://jira.jboss.com/jira/browse/JBESB-1796 Project: JBoss ESB Issue Type: Bug Security Level: Public(Everyone can see) Components: Content Based Routing Affects Versions: 4.3 Environment: Java 1.5 or 6.0 JBoss 4.2.2 GA JBoss ESB 4.2.1 or 4.3 Memory settings: -Xms256m -Xmx256m -XX:MaxPermSize=128m Reporter: Maurice Zeijen Assigned To: Kevin Conner Fix For: 4.4 Attachments: memory_leak_cbr.zip may have found a memory leak in the Content Based Router in both JBoss ESB 4.2.1 and 4.3. I noticed the problem at my Job with a production JBoss ESB 4.2.1 CP2 because it regularly crashed because the memory run out. After doing some memory analysis I found that the problem was with the content based router. To reliably reproduce the problem I created a sample project using the simple_cbr sample. I attached the sample project to this issueu. I also included an export from a memory analysis of a memory dump. In that dump you can clearly see that the org.drools.base.FireAllRulesRuleBaseUpdateListener objects are piling up. Because the problem is within Drools I am not sure if the problem is really in the ESB. Simply unpack the project within the sample/quickstarts directoy to make it work.
