    waiting thread in jboss 4

    mike just Master

      I am not sure if I am questioning in the right place, but I am really eager to know what is going on with my system. It is happening only in recent days but I do not know what changes cause this.


      Here is a piece of jstack trace for the stuck thread.



      "UIL2.SocketManager.WriteTask#4 client=" daemon prio=6 tid=0x000000000de5e800 nid=0x21dc in Object.wait() [0x000000001688f000]
         java.lang.Thread.State: WAITING (on object monitor)
                at java.lang.Object.wait(Native Method)
                at java.lang.Object.wait(Object.java:485)
                at EDU.oswego.cs.dl.util.concurrent.LinkedQueue.take(LinkedQueue.java:122)
                - locked <0x0000000603772710> (a java.lang.Object)
                at org.jboss.mq.il.uil2.SocketManager$WriteTask.run(SocketManager.java:484)
                at java.lang.Thread.run(Thread.java:662)
         Locked ownable synchronizers:
                - None


      There are really a lot more than such one piece. Could anybody suggest me what the possible reason is or how to debug this problem?


      Attached is the entire jstack log.
