>  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.
