如何檢查對象

當我使用jstack檢查過程中，冰絲的等待，我有這個日誌：如何檢查對象

"poolTaskThread-4" prio=10 tid=0x00007f09300ff800 nid=0x69ce in Object.wait() [0x00007f0aa5271000]

，並有許多其他類似this.First我想這是因爲冰的連接超時設置問題，因爲我在管線147找到Outgoing.java是這樣的：

 int timeout = connection.timeout(); 
       while(_state == StateInProgress && !timedOut) 
       { 
        try 
        { 
         if(timeout >= 0) 
         { 
          wait(timeout); 

          if(_state == StateInProgress) 
          { 
           timedOut = true; 
          } 
         } 
         else 
         { 
          wait(); 
         } 
        } 
        catch(InterruptedException ex) 
        { 
        } 
       } 
      } 

      if(timedOut) 
      { 
       // 
       // Must be called outside the synchronization of 
       // this object 
       // 
       connection.exception(new Ice.TimeoutException()); 

       // 
       // We must wait until the exception set above has 
       // propagated to this Outgoing object. 
       // 
       synchronized(this) 
       { 
        while(_state == StateInProgress) 
        { 
         try 
         { 
          wait(); //147 line 
         } 
         catch(InterruptedException ex) 
         { 
         } 
        } 
       } 
      }

所以我必須添加的第Ice.Override.Connection = 200000，但問題出現得越早，我應該怎麼辦關於冰線~~

冰有一個paramters被稱爲Ice.CacheMessageBuffer，你可以設置這個

Ice.CacheMessageBuffers=0

這會不會致電directbuffer，你可以嘗試它，它會提高JVM GC。
