[rules-users] OutOfMemoryError happens when dynamic loading of Rules from Guvnor frequently

I am using Drools 5.1.1 to design our rule engine, the rule engine need to dynamic loading of rules from Guvnor because our marking team need to change the rules frequently(about 40~100 times every day), we have over 5000 rules in Guvnor. This is my code ahout that: public KnowledgeBase getKnowledgeBase() { // hold a static reference in class if(kagent != null) { return kagent.getKnowledgeBase(); } ResourceChangeScannerConfiguration sconf = ResourceFactory.getResourceChangeScannerService().newResourceChangeScannerConfiguration(); sconf.setProperty("drools.resource.scanner.interval", "5"); ResourceFactory.getResourceChangeScannerService().configure(sconf); ResourceFactory.getResourceChangeScannerService().start(); ResourceFactory.getResourceChangeNotifierService().start(); kagent = KnowledgeAgentFactory.newKnowledgeAgent("myagent"); kagent.applyChangeSet(ResourceFactory.newClassPathResource("changeset-url.xml")); return kagent.getKnowledgeBase(); } This is content of changeset-url.xml: <change-set xmlns='http://drools.org/drools-5.0/change-set' xmlns:xs='http://www.w3.org/2001/XMLSchema-instance' xs:schemaLocation='http://drools.org/drools-5.0/change-set http://anonsvn.jboss.org/repos/labs/labs/jbossrules/trunk/drools-api/src/... <add <resource source='http://localhost:8080/drools-guvnor/org.drools.guvnor.Guvnor/package/PackageName/snapshot_release' type='PKG' / </add</change-set After i start my service, i found each time When i rebuild package and created new snapshot to snapshot_release, my service indeed can find the changing and start to reload rules from guvnor, but memory increased about 50M, it didn't down even if the reloading had finished. After i reput do this step many times(about 25 times), OutOfMemoryError happened. So, I want to know, why memory increased continually？It sames drools didn't do garbage collection. Has anyone experienced this? Thanks - Oliver -- View this message in context: http://drools.46999.n3.nabble.com/OutOfMemoryError-happens-when-dynamic-l...
