同命同命，可惜问题我不大明白，遗憾

[边城狂人]

虚拟机报错可能是由于Java的Bug造成的，也可能是虚拟机内存溢出等造成的，这个只能报告给Sun了，一般人不咋看得懂

[atec2000]

多谢olivesoup的长时间关注。现在只知道不定期地会crash，OS系统方面也没有什么特别的变化呀。

[olivesoup]

我过完年回来看这贴还在这呢，都一年了啊也没解决

不过面对你的问题感觉有些力不从心，惭愧
建议你联系一下java基础板块的斑竹java2000_net，他比较热心，而且技术出色

[xql80329]

呵呵 LS 的建议考虑考虑
我提供给你java2000_net 他自己的论坛 地址 你把问题放上去 他会给你看的

[atec2000]

谢谢各位关注。到现在还没有解决，解决了我会把解决方法贴出来（现在已经升级到JDK1.6了，新的错误情况请看下贴）。祝大家情人节快乐！

[olivesoup]

一直在想，这种错误应该是不常见的啊，lz是在什么情况下出现这种情况的，有什么特殊的诱因吗

[atec2000]

呵呵 很感谢olivesoup和xql80329的关心。这个问题现在有所进展。大幅削减了Log输出后，已经4天没有crash了。由于用了一个第三方的Log工具，当时不知道这个Log工具会向 标准输出 也输出Log。怀疑非常频繁的输出大量的Log到控制台上JVM的处理有问题（也怀疑本身频繁的输出大量的Log到文件中JVM的处理有问题）。（每1秒钟就输出170k的Log）。
是不是这个原因还不能最终确定（因为时间还不够长，不能保证真的没有问题了）。

另外，有一点信息也交流一下：
JDK1.6修改了大量垃圾收集器的问题，如果JDK1.5出现了垃圾收集器引起的crash，可以升级到JDK1.6试试。

[atec2000]

这个问题就如上贴这样解决了，呵呵。

不错，还有就是需要做ThreadDump看看。大量的IO是会导致性能问题的。

[lswfly]

我现在又遇到几乎同样的问题了，一个军方项目
四台机器中，两台可以正常使用，其余两台就不行
总是crash，而且机器配置一样，软件配置几乎也一样
目前正在sun网站上查找原因
这个项目就是一个普通的web项目，真是郁闷了

[lswfly]

这个问题比较奇怪，虽说是jdk的一个bug
但查了很久仍为找到确切的解决办法，
现将我的解决过程讲一下：
1.EXCEPTION_ACCESS_VIOLATION ”意味着Java应用Crash的时候，正在运行JVM自己的代码，而不是外部的Java代码或其他类库代码
2.根据log信息中的
# Problematic frame:
# C [ntdll.dll+0x18fea]
可以判断是加载本地方法时出错.
但解决办法仍然没找到
我试着卸载jdk然后安装最新版本仍然存在。
后怀疑是软件冲突，发现没有问题的机器上安装的卡巴
有问题的安装的都是诺顿
于是卸载到诺顿后问题解决
看来有时候杀毒软件与jdk还真是不太兼容

[atec2000]

这个帖子现在回过头来看应该不是jdk_1.5.0的问题，应该是向标准输出太多太频繁了虚拟机处理不过来的问题。输出改少后就解决了。只是当时还把jdk升级到1.6了，以为也有关系。
为什么这么说呢，因为Log里面有：
Java_sun_awt_X11_XToolkit_waitForEvents+0x33
猜想是刷新terminal窗口的时候用的吧。

lswfly所说的诺顿的问题也是另外一种经验吧，谢谢分享。
