Hello, In my tests of the 4.0.3, I have some : java.lang.OutOfMemoryError. So, I try a simple test with 10.000 sequential execution of 1 rule with no context and just a workingmemorylogger and I have the error : java.lang.OutOfMemoryError: Java heap space My code is : public class ExecReglesMemotyTest { private static final Reader DRL = new InputStreamReader(ExecReglesMemotyTest.class .getResourceAsStream("/rules/exemple.drl")); private static final String FICHIER_LOG = "session"; /** * @param args */ public static void main(String[] args) { try { PackageBuilder builder = new PackageBuilder(); builder.addPackageFromDrl(DRL); RuleBase ruleBase = RuleBaseFactory.newRuleBase(); ruleBase.addPackage(builder.getPackage()); for (int i = 0; i < 10000; i++) { StatefulSession session = ruleBase.newStatefulSession(); WorkingMemoryFileLogger logger = new WorkingMemoryFileLogger(session); logger.setFileName(FICHIER_LOG); session.fireAllRules(); logger.writeToDisk(); session.dispose(); } } catch (Exception e) { // TODO Auto-generated catch block e.printStackTrace(); } } } with this rule (doesn't matter): #created on: Fri Nov 09 15:48:45 CET 2007 package initPackage #list any import classes here. rule "ERG9" when then end I try this in 4.0.1, and it's working (no OutOfMemoryError) What's the problem ? thanks for any information, V.

Hello, I add this 4 lines in my code before the session.dispose() and the problem disapear : session.removeEventListener((WorkingMemoryEventListener)logger); session.removeEventListener((AgendaEventListener)logger); session.removeEventListener((RuleFlowEventListener)logger); session.removeEventListener((RuleBaseEventListener)logger); regards, V. vdelbart wrote: > > Good morning, > > I found a workaround : don't use the WorkingMemoryFileLogger ! > > I create an issue : http://jira.jboss.com/jira/browse/JBRULES-1325 > > regards, > > V. > > > vdelbart wrote: >> >> Hello, >> >> In my tests of the 4.0.3, I have some : java.lang.OutOfMemoryError. >> >> So, I try a simple test with 10.000 sequential execution of 1 rule with >> no context and just a workingmemorylogger and I have the error : >> java.lang.OutOfMemoryError: Java heap space >> >> My code is : >> >> public class ExecReglesMemotyTest >> { >> >> private static final Reader DRL = new >> InputStreamReader(ExecReglesMemotyTest.class >> .getResourceAsStream("/rules/exemple.drl")); >> >> private static final String FICHIER_LOG = "session"; >> >> /** >> * @param args >> */ >> public static void main(String[] args) >> { >> try >> { >> PackageBuilder builder = new PackageBuilder(); >> builder.addPackageFromDrl(DRL); >> RuleBase ruleBase = RuleBaseFactory.newRuleBase(); >> ruleBase.addPackage(builder.getPackage()); >> for (int i = 0; i < 10000; i++) >> { >> StatefulSession session = ruleBase.newStatefulSession(); >> WorkingMemoryFileLogger logger = new >> WorkingMemoryFileLogger(session); >> logger.setFileName(FICHIER_LOG); >> session.fireAllRules(); >> logger.writeToDisk(); >> session.dispose(); >> } >> >> } >> catch (Exception e) >> { >> // TODO Auto-generated catch block >> e.printStackTrace(); >> } >> } >> } >> >> with this rule (doesn't matter): >> #created on: Fri Nov 09 15:48:45 CET 2007 >> package initPackage >> >> #list any import classes here. >> >> rule "ERG9" >> when >> >> then >> >> end >> >> I try this in 4.0.1, and it's working (no OutOfMemoryError) >> >> What's the problem ? >> >> thanks for any information, >> >> V. >> >> >> > > -- View this message in context: http://www.nabble.com/java.lang.OutOfMemoryError%3A-Java-heap-space-tf477...

Has this issue been fixed, or is it still necessary to remove any event listeners so that the session is freed? -- View this message in context: http://drools.46999.n3.nabble.com/java-lang-OutOfMemoryError-Java-heap-sp...
