> 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.
