Summary: High CPU usage after hibernate/suspend and wake up Windows Key: NETBEANS-2214 URL: https://issues.apache.org/jira/browse/NETBEANS-2214 Project: NetBeans Issue Type: Bug Affects Versions: 10.0 Environment: Windows 7 Java 8 u181 Reporter: Danton Estevam Pinto Attachments: jstack_-l_PID.txt After hibernate/suspend and wake up Windows with Netbeans running on it, Netbeans starts a high CPU usage. After Windows wake up, by analysing Thread tab of the Netbenas process on Process Explorer, I see one threads remaining in infinite loop. It seems there is a workaround like reported here: [https://github.com/hazelcast/hazelcast/pull/7998] Thread Stack: "WebSocketServer" #47 daemon prio=1 os_prio=-2 tid=0x000000001f132000 nid=0x10b0 runnable [0x000000002a2df000] java.lang.Thread.State: RUNNABLE at sun.nio.ch.WindowsSelectorImpl$SubSelector.poll0(Native Method) at sun.nio.ch.WindowsSelectorImpl$SubSelector.poll(WindowsSelectorImpl.java:296) at sun.nio.ch.WindowsSelectorImpl$SubSelector.access$400(WindowsSelectorImpl.java:278) at sun.nio.ch.WindowsSelectorImpl.doSelect(WindowsSelectorImpl.java:159) at sun.nio.ch.SelectorImpl.lockAndDoSelect(SelectorImpl.java:86) - locked <0x00000000c70c3798> (a sun.nio.ch.Util$3) - locked <0x00000000c70c3788> (a java.util.Collections$UnmodifiableSet) - locked <0x00000000c70c32e8> (a sun.nio.ch.WindowsSelectorImpl) at sun.nio.ch.SelectorImpl.select(SelectorImpl.java:97) at sun.nio.ch.SelectorImpl.select(SelectorImpl.java:101) at org.netbeans.modules.netserver.SocketFramework.doRun(SocketFramework.java:97) at org.netbeans.modules.netserver.SocketServer.run(SocketServer.java:53) at org.openide.util.RequestProcessor$Task.run(RequestProcessor.java:1418) at org.netbeans.modules.openide.util.GlobalLookup.execute(GlobalLookup.java:45) at org.openide.util.lookup.Lookups.executeWith(Lookups.java:278) at org.openide.util.RequestProcessor$Processor.run(RequestProcessor.java:2033) -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: commits-unsubscr...@netbeans.apache.org For additional commands, e-mail: commits-h...@netbeans.apache.org For further information about the NetBeans mailing lists, visit: https://cwiki.apache.org/confluence/display/NETBEANS/Mailing+lists
