[ https://issues.jboss.org/browse/RF-13250?page=com.atlassian.jira.plugin.s... ] Juraj Húska edited comment on RF-13250 at 2/19/14 11:58 AM: ------------------------------------------------------------ I have reproduced the issue with the description provided by community also with RichFaces 5.x version. The reproducer can be found at [this|https://github.com/richfaces/richfaces/tree/RF-13250] branch. Test script will start an Arquillian test, which will start JBoss AS 7.1.1.Final instance with 256Mb max heap size. It will then try to simulate 4 users (not simultaneous), receiving push events. Another script is in the meantime making invalid push requests causing the heap exceeding its allowed size. Steps to reproduce: # checkout referenced branch # issue: {code} cd examples/push-demo/ mvn clean verify -Dtest.timeout=2160000 {code} # from another terminal window issue: {code} cd examples/push-demo/ bash malformedPushRequestScript.sh {code} # where {{-Dtest.timeout}} is timeout for running the test in milliseconds, e.g. 2160000 == 6 hours, I was able to reproduce it in 4 hours # after e.g. 4 hours check that the test output contains {{OOM exception}} This OOM exceptions which can be found in the server log: {code} 16:05:28,635 ERROR [org.apache.catalina.core.ContainerBase.[jboss.web].[default-host].[/push].[Faces Servlet]] (http--127.0.0.1-8080-3) Servlet.service() for servlet Faces Servlet threw exception: java.lang.OutOfMemoryError: GC overhead limit exceeded at java.util.Arrays.copyOfRange(Arrays.java:2694) [rt.jar:1.7.0_45] at java.lang.String.<init>(String.java:203) [rt.jar:1.7.0_45] at java.lang.String.substring(String.java:1913) [rt.jar:1.7.0_45] at java.lang.String.trim(String.java:2732) [rt.jar:1.7.0_45] at com.sun.faces.facelets.util.DevTools.writeStart(DevTools.java:419) [jsf-impl-2.1.7-jbossorg-2.jar:] at com.sun.faces.facelets.util.DevTools.writeComponent(DevTools.java:245) [jsf-impl-2.1.7-jbossorg-2.jar:] at com.sun.faces.facelets.util.DevTools.writeComponent(DevTools.java:264) [jsf-impl-2.1.7-jbossorg-2.jar:] at com.sun.faces.facelets.util.DevTools.writeComponent(DevTools.java:264) [jsf-impl-2.1.7-jbossorg-2.jar:] at com.sun.faces.facelets.util.DevTools.debugHtml(DevTools.java:128) [jsf-impl-2.1.7-jbossorg-2.jar:] at com.sun.faces.renderkit.RenderKitUtils.renderHtmlErrorPage(RenderKitUtils.java:1159) [jsf-impl-2.1.7-jbossorg-2.jar:] at com.sun.faces.context.ExceptionHandlerImpl.throwIt(ExceptionHandlerImpl.java:273) [jsf-impl-2.1.7-jbossorg-2.jar:] at com.sun.faces.context.ExceptionHandlerImpl.handle(ExceptionHandlerImpl.java:142) [jsf-impl-2.1.7-jbossorg-2.jar:] at com.sun.faces.lifecycle.Phase.doPhase(Phase.java:119) [jsf-impl-2.1.7-jbossorg-2.jar:] at com.sun.faces.lifecycle.LifecycleImpl.render(LifecycleImpl.java:139) [jsf-impl-2.1.7-jbossorg-2.jar:] at javax.faces.webapp.FacesServlet.service(FacesServlet.java:594) [jboss-jsf-api_2.1_spec-2.0.1.Final.jar:2.0.1.Final] at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:329) [jbossweb-7.0.13.Final.jar:] at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:248) [jbossweb-7.0.13.Final.jar:] at org.apache.catalina.core.StandardWrapperValve.invoke(StandardWrapperValve.java:275) [jbossweb-7.0.13.Final.jar:] at org.apache.catalina.core.StandardContextValve.invoke(StandardContextValve.java:161) [jbossweb-7.0.13.Final.jar:] at org.jboss.as.web.security.SecurityContextAssociationValve.invoke(SecurityContextAssociationValve.java:153) [jboss-as-web-7.1.1.Final.jar:7.1.1.Final] at org.apache.catalina.core.StandardHostValve.invoke(StandardHostValve.java:155) [jbossweb-7.0.13.Final.jar:] at org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java:102) [jbossweb-7.0.13.Final.jar:] at org.apache.catalina.core.StandardEngineValve.invoke(StandardEngineValve.java:109) [jbossweb-7.0.13.Final.jar:] at org.apache.catalina.connector.CoyoteAdapter.service(CoyoteAdapter.java:368) [jbossweb-7.0.13.Final.jar:] at org.apache.coyote.http11.Http11Processor.process(Http11Processor.java:877) [jbossweb-7.0.13.Final.jar:] at org.apache.coyote.http11.Http11Protocol$Http11ConnectionHandler.process(Http11Protocol.java:671) [jbossweb-7.0.13.Final.jar:] at org.apache.tomcat.util.net.JIoEndpoint$Worker.run(JIoEndpoint.java:930) [jbossweb-7.0.13.Final.jar:] at java.lang.Thread.run(Thread.java:744) [rt.jar:1.7.0_45] {code} and {code} 6:07:41,281 WARN [org.hornetq.core.remoting.server.impl.RemotingServiceImpl] (hornetq-failure-check-thread) GC overhead limit exceeded: java.lang.OutOfMemoryError: GC overhead limit exceeded {code}. was (Author: jhuska): I have reproduced the issue with the description provided by community.
