[ https://issues.jboss.org/browse/WFWIP-28?page=com.atlassian.jira.plugin.s... ] Francesco Nigro commented on WFWIP-28: -------------------------------------- Looking at https://mw-messaging-qe-jenkins.rhev-ci-vms.eng.rdu2.redhat.com/view/EAP/... most of the collected metrics are simply wrong (CPU utilisation = -100 File descriptors = -1) probably due to a missing/killed JVM process: my suspect (to be verified) are toward a OOM killer action. I suppose that collecting the Sosreport and using a static node to avoid anything related the process to be cleaned up with the VM will help to find where the issue is: ATM just the collected logs aren't enough. FYI the mentioned job has this log that shows the problem and when it has happened: {code:java} 05:20:49,073 pool-2-thread-2 DEBUG [org.jboss.qa.resourcemonitor.CpuLoadMeasurement:70] getCpu attribute ProcessCpuLoad returned 0.01946859311864822 05:20:49,085 pool-2-thread-2 DEBUG [org.jboss.qa.resourcemonitor.CpuLoadMeasurement:70] getCpu attribute SystemCpuLoad returned 0.1457247132429614 05:20:49,092 pool-1-thread-4 DEBUG [org.jboss.qa.resourcemonitor.CpuLoadMeasurement:70] getCpu attribute ProcessCpuLoad returned -1 05:20:49,100 pool-1-thread-3 WARN [org.jboss.qa.resourcemonitor.ThreadMeasurement:43] Error reseting peak counter 05:20:49,102 pool-1-thread-4 DEBUG [org.jboss.qa.resourcemonitor.CpuLoadMeasurement:70] getCpu attribute SystemCpuLoad returned -1 05:20:49,145 Thread-4321 (ActiveMQ-client-global-threads) TRACE [org.apache.activemq.artemis.core.client.impl.ClientSessionFactoryImpl:525] AMQ214026: Failure captured on connectionID=e7fb5df2, performing failover or reconnection now ActiveMQNotConnectedException[errorType=NOT_CONNECTED message=AMQ119006: Channel disconnected] at org.apache.activemq.artemis.core.client.impl.ClientSessionFactoryImpl.connectionDestroyed(ClientSessionFactoryImpl.java:353) at org.apache.activemq.artemis.core.remoting.impl.netty.NettyConnector$Listener$1.run(NettyConnector.java:1050) at org.apache.activemq.artemis.utils.actors.OrderedExecutor.doTask(OrderedExecutor.java:42) at org.apache.activemq.artemis.utils.actors.OrderedExecutor.doTask(OrderedExecutor.java:31) at org.apache.activemq.artemis.utils.actors.ProcessorBase.executePendingTasks(ProcessorBase.java:66) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1149) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:624) at java.lang.Thread.run(Thread.java:748) 05:20:49,146 Thread-4327 (ActiveMQ-client-global-threads) TRACE [org.apache.activemq.artemis.core.client.impl.ClientSessionFactoryImpl:525] AMQ214026: Failure captured on connectionID=ca7b4f32, performing failover or reconnection now ActiveMQNotConnectedException[errorType=NOT_CONNECTED message=AMQ119006: Channel disconnected] at org.apache.activemq.artemis.core.client.impl.ClientSessionFactoryImpl.connectionDestroyed(ClientSessionFactoryImpl.java:353) at org.apache.activemq.artemis.core.remoting.impl.netty.NettyConnector$Listener$1.run(NettyConnector.java:1050) at org.apache.activemq.artemis.utils.actors.OrderedExecutor.doTask(OrderedExecutor.java:42) at org.apache.activemq.artemis.utils.actors.OrderedExecutor.doTask(OrderedExecutor.java:31) at org.apache.activemq.artemis.utils.actors.ProcessorBase.executePendingTasks(ProcessorBase.java:66) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1149) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:624) at java.lang.Thread.run(Thread.java:748) {code} -- This message was sent by Atlassian JIRA (v7.5.0#75005)
