情况是这样的。我在压一个JAVA写的游戏服务器。

压测服务器环境
   硬件：
  CPU： intel core i3-3240  3.40GHz 3.40GHz
   内存：4.0G
   硬盘：希捷 ST500DM002 500G 7200转/分
   固态硬盘：无
   软件:
     操作系统：windows7 旗舰版
     JAVA：    1.7.0_51
     MySQL：   5.5.36

400个连接连上。 CPU不高，过一会之后CPU只有0.01%，内存1.1G，过10多分钟后，导致 服务器卡死。。不能响应任何socket请求。关闭压测的客户端之后，客户端的连接并没有关闭，出现大量的FIN_WAIT_1（应该是服务器没有响应ACK）。这个时候jvisualvm连接不上服务器（一直loading状态）。由于不能jvisualvm上去，我就直接用jstack dump 线程信息。

jstack出来的结果如下(不带-F）：

我用jstack -F (带-F) dump出来的结果如下，这里由于文本限制，少了很多东西：

Deadlock Detection:

No deadlocks found.

Thread 7: (state = BLOCKED)
 - java.lang.Object.wait(long) @bci=0 (Compiled frame; information may be imprecise)
 - java.lang.Object.wait() @bci=2, line=503 (Interpreted frame)
 - java.lang.ref.Reference$ReferenceHandler.run() @bci=46, line=133 (Interpreted frame)

这里有几个简单的问题问一下：
1：为什么jstack -F 抓到的包都是BLOCKED的呢？
2：jstack -F 打出的thread X 。比如 Thread 7: (state = BLOCKED) 这里的 id为7的线程和jstack（不带-F）的哪个线程对应呢？而且发现jstack -F 所打的信息感觉不多啊？又都是block 没有什么价值。

上面是几个简单的问题，其实更进一步的问题是。
1：为什么我服务器会无响应。我开始以为是死锁。但是jstack打出来的信息没有死锁信息。
2：为什么压测的客户端到了一定数量就和服务器断开连接？ 出现的异常如下：
 

  java.io.IOException: 远程主机强迫关闭了一个现有的连接。
	at sun.nio.ch.SocketDispatcher.read0(Native Method)

2015-01-30 16:36:56 [ERROR]MinaSocketHandler的exceptionCaught方法
org.apache.mina.core.write.WriteToClosedSessionException
  

3：解决这种问题，一般的思路是什么。其实我更像让Red大教我们一下思路，一般这种虚拟机方面的问题，分几步解决。分别怎么查找问题。

谢谢了。（开始发了一版。超过限制，把一些内容修改后再发一次）

我怀疑还是死锁问题，但是jstack -F（加了-F） 打出来是No deadlocks found. 。但是我总感觉jstack -F打出来的都是block。我总觉得不对。所以我觉得他打出来的No deadlocks found这个也是不可信的。

还有个问题：
比如
- locked <0x00000000c2389e38>
in Object.wait() [0x0000000009a5e000] 
waiting on condition [0x000000000fb5f000]

红色标注是对象ID吧。如果是，怎么看是哪个对象呢?如果不是，那是什么呢？

你好
这个问题解决没有，想学习一下

解决了！
