So in a corrosponding thread dump for every failed connection there will be the following dead entries: ############################################################ "Remoting "endpoint" Accept" #215802 daemon prio=5 os_prio=0 tid=0x00007f48dc21a000 nid=0x4e8e runnable [0x00007f48894d6000] java.lang.Thread.State: RUNNABLE at sun.nio.ch.EPollArrayWrapper.epollWait(Native Method) at sun.nio.ch.EPollArrayWrapper.poll(EPollArrayWrapper.java:269) at sun.nio.ch.EPollSelectorImpl.doSelect(EPollSelectorImpl.java:93) at sun.nio.ch.SelectorImpl.lockAndDoSelect(SelectorImpl.java:86) - locked <0x00000000f01d1d10> (a sun.nio.ch.Util$3) - locked <0x00000000f01d1d00> (a java.util.Collections$UnmodifiableSet) - locked <0x00000000f01d1be8> (a sun.nio.ch.EPollSelectorImpl) at sun.nio.ch.SelectorImpl.select(SelectorImpl.java:97) at sun.nio.ch.SelectorImpl.select(SelectorImpl.java:101) at org.xnio.nio.WorkerThread.run(WorkerThread.java:509) "Remoting "endpoint" I/O-1" #215801 daemon prio=5 os_prio=0 tid=0x00007f48dc08c000 nid=0x4e8d runnable [0x00007f4885ea0000] java.lang.Thread.State: RUNNABLE at sun.nio.ch.EPollArrayWrapper.epollWait(Native Method) at sun.nio.ch.EPollArrayWrapper.poll(EPollArrayWrapper.java:269) at sun.nio.ch.EPollSelectorImpl.doSelect(EPollSelectorImpl.java:93) at sun.nio.ch.SelectorImpl.lockAndDoSelect(SelectorImpl.java:86) - locked <0x00000000f01cc188> (a sun.nio.ch.Util$3) - locked <0x00000000f01cc178> (a java.util.Collections$UnmodifiableSet) - locked <0x00000000f01cc060> (a sun.nio.ch.EPollSelectorImpl) at sun.nio.ch.SelectorImpl.select(SelectorImpl.java:97) at sun.nio.ch.SelectorImpl.select(SelectorImpl.java:101) at org.xnio.nio.WorkerThread.run(WorkerThread.java:509) ############################################################ NitinRanjan suggested to patch the close() method of RemotingConnector.java which is responsible for closing the endpoint threads and others. In case of connection not established the state is UNUSED which makes the close method to return without closing the endpoint thread. -- This message was sent by Atlassian JIRA (v7.5.0#75005)
