Re: [rules-users] Out of Memory Issue of JBoss Engine deployed on IBM WAS 6.0.2.7

Hi All, I ran into OOM (Out of Memory) issue of JBoss Engine deployed on IBM WAS 6.0.2.7. Below is the log … [Loaded org.antlr.runtime.DFA from file:/D:/WebSphere/AppServer/profiles/AppSrv01/installedApps/xxxNode02Cell/xxx.ear/lib/antlr-3.0ea8.jar] [Loading superclass and interfaces of org/antlr/runtime/DFA] [Preparing org/antlr/runtime/DFA] [Loaded org.antlr.runtime.DFA$State from file:/D:/WebSphere/AppServer/profiles/AppSrv01/installedApps/xxxNode02Cell/xxxApplications.ear/lib/antlr-3.0ea8.jar] [Loading superclass and interfaces of org/antlr/runtime/DFA$State] [Loaded org.drools.lang.RuleParserLexer$1 from file:/D:/WebSphere/AppServer/profiles/AppSrv01/installedApps/xxxNode02Cell/xxxApplications.ear/lib/drools-compiler-3.0.jar] [Loading superclass and interfaces of org/drools/lang/RuleParserLexer$1] [Loaded org.drools.lang.RuleParserLexer$2 from file:/D:/WebSphere/AppServer/profiles/AppSrv01/installedApps/xxxNode02Cell/ xxxApplications.ear/lib/drools-compiler-3.0.jar] [Loading superclass and interfaces of org/drools/lang/RuleParserLexer$2] [Loaded org.drools.lang.RuleParserLexer$3 from file:/D:/WebSphere/AppServer/profiles/AppSrv01/installedApps/xxxNode02Cell/ xxxApplications.ear/lib/drools-compiler-3.0.jar] [Loading superclass and interfaces of org/drools/lang/RuleParserLexer$3] [Loaded org.drools.lang.RuleParserLexer$4 from file:/D:/WebSphere/AppServer/profiles/AppSrv01/installedApps/xxxNode02Cell/ xxxApplications.ear/lib/drools-compiler-3.0.jar] [Loading superclass and interfaces of org/drools/lang/RuleParserLexer$4] ….

Any idea why this happens and how to fix this?
