[jboss-user] [jBPM] - Console + Designer = jboss OutOfMemoryError: GC overhead limit exceeded

Renzo Tomaselli [http://community.jboss.org/people/Tomarenz] created the discussion "Console + Designer = jboss OutOfMemoryError: GC overhead limit exceeded" To view the discussion, visit: http://community.jboss.org/message/620395#620395 -------------------------------------------------------------- Hi all, I would like to collect experience/comments on this issue, occurring at random but very often in my case. I have just two simple processes in Guvnor, 8 nodes each. One is BPMN2-ExclusiveSplit and the other is very similar. The defaultPackage has been successfully built. I can either run the Console to list processes, or I can run the Designer to view process definitions, edit them and rebuild the package. But as soon as I switch from an application to the other, soon I get a jboss error as reported in the subject. I also tried to set -XX:-UseGCOverheadLimit, without any success. Things get blocked soon because of "java.lang.OutOfMemoryError: Java heap space". As an example of a failing sequence: - start the designer, select defaultPackage, list processes. - open both processes. - from the browser go to the rest url /gwt-console-server/rs/process/definitions, getting: | 2011-08-10 16:23:34,285 INFO  [STDOUT] (http-localhost%2F127.0.0.1-8080-3) INFO  10-08 16:23:34,285 (PackageDeploymentServlet.java:execute:144) | PackageIsSource: false | 2011-08-10 16:23:36,937 INFO  [STDOUT] (http-localhost%2F127.0.0.1-8080-2) Loading process from Guvnor: boh 2011-08-10 16:23:36,937 INFO  [STDOUT] (http-localhost%2F127.0.0.1-8080-2) Loading process from Guvnor: BPMN2-ExclusiveSplit 2011-08-10 16:23:42,412 INFO  [STDOUT] (http-localhost%2F127.0.0.1-8080-2) Loading process from file system: Evaluation.bpmn 2011-08-10 16:23:55,750 WARN  [org.jboss.detailed.classloader.ClassLoaderManager] (http-localhost%2F127.0.0.1-8080-2) Unexpected error during load of:org.drools.rule.builder.dialect.java.parser.JavaParser$DFA172 java.lang.OutOfMemoryError: GC overhead limit exceeded | | at java.util.Arrays.copyOf(Arrays.java:2786) | | | at java.io.ByteArrayOutputStream.write(ByteArrayOutputStream.java:94) | | | at org.jboss.classloader.plugins.ClassLoaderUtils.readBytes(ClassLoaderUtils.java:212) | | | at org.jboss.classloader.plugins.ClassLoaderUtils.loadByteCode(ClassLoaderUtils.java:148) | | | at org.jboss.classloader.spi.base.BaseClassLoader$2.run(BaseClassLoader.java:543) | | | at org.jboss.classloader.spi.base.BaseClassLoader$2.run(BaseClassLoader.java:532) | | | at java.security.AccessController.doPrivileged(Native Method) | | | at org.jboss.classloader.spi.base.BaseClassLoader.loadClassLocally(BaseClassLoader.java:530) | | | at org.jboss.classloader.spi.base.BaseClassLoader.loadClassLocally(BaseClassLoader.java:507) | | | at org.jboss.classloader.spi.base.BaseDelegateLoader.loadClass(BaseDelegateLoader.java:134) | | | at org.jboss.classloader.spi.filter.FilteredDelegateLoader.loadClass(FilteredDelegateLoader.java:131) | | | at org.jboss.classloader.spi.base.ClassLoadingTask$ThreadTask.run(ClassLoadingTask.java:452) | | | at org.jboss.classloader.spi.base.ClassLoaderManager.nextTask(ClassLoaderManager.java:251) | | | at org.jboss.classloader.spi.base.ClassLoaderManager.process(ClassLoaderManager.java:150) | | | at org.jboss.classloader.spi.base.BaseClassLoaderDomain.loadClass(BaseClassLoaderDomain.java:265) | | | at org.jboss.classloader.spi.base.BaseClassLoaderDomain.loadClass(BaseClassLoaderDomain.java:1119) | | | at org.jboss.classloader.spi.base.BaseClassLoader.loadClassFromDomain(BaseClassLoader.java:798) | | | at org.jboss.classloader.spi.base.BaseClassLoader.loadClass(BaseClassLoader.java:441) | | | at java.lang.ClassLoader.loadClass(ClassLoader.java:248) | | | at org.drools.rule.builder.dialect.java.parser.JavaParser.<init>(JavaParser.java:11723) | | | at org.drools.rule.builder.dialect.java.parser.JavaParser.<init>(JavaParser.java:219) | | | at org.drools.rule.builder.dialect.java.JavaExprAnalyzer.analyzeBlock(JavaExprAnalyzer.java:90) | | | at org.drools.rule.builder.dialect.java.JavaDialect.analyzeBlock(JavaDialect.java:258) | | | at org.jbpm.process.builder.dialect.java.JavaActionBuilder.build(JavaActionBuilder.java:56) | | | at org.jbpm.process.builder.ExtendedNodeBuilder.buildAction(ExtendedNodeBuilder.java:40) | | | at org.jbpm.process.builder.ExtendedNodeBuilder.build(ExtendedNodeBuilder.java:29) | | | at org.jbpm.process.builder.EventBasedNodeBuilder.build(EventBasedNodeBuilder.java:19) | | | at org.jbpm.process.builder.WorkItemNodeBuilder.build(WorkItemNodeBuilder.java:18) | | | at org.jbpm.compiler.ProcessBuilderImpl.processNodes(ProcessBuilderImpl.java:215) | | | at org.jbpm.compiler.ProcessBuilderImpl.buildNodes(ProcessBuilderImpl.java:201) | | | at org.jbpm.compiler.ProcessBuilderImpl.buildProcess(ProcessBuilderImpl.java:165) | | | at org.jbpm.compiler.ProcessBuilderImpl.addProcessFromXml(ProcessBuilderImpl.java:254) | ...
