我们有一个基于Jboss的网络应用程序，已经生产了几年;在过去的18个月里，它从未下降过。然而，在最近两天，jvm已经坠毁了4次。
当JVM崩溃时，我们收到一条错误报告，我正在努力破译。我查看了其他几个崩溃报告（在这个网站和其他网站上），但没有一个与我们完全一样;因为我是读新手的新手，我不知道我错过了什么。
[编辑崩溃报告以添加更多信息]
我有四份崩溃报告......我会发布其中两份（为了简洁起见，图书馆除外），以防有助于诊断问题。 4个看起来完全一样。我只发帖2，因为身体有30000个限制。

我做过的其他事情：
1.我已将-Xcheck：jni添加到JVM选项中，以查看本机库是否存在某种问题。
2.打开Jboss上的调试，看看我是否可以在JVM死之前捕获更多信息。
非常感谢您的建议！

所以，服务器启动了几天......然后第五次再次崩溃。我在这里添加了一个新问题的新问题：https://stackoverflow.com/questions/6005976/jboss-hotspot-jvm-crashing-again
运行H / W诊断后更新 刚刚让GoDaddy运行诊断程序后收到了以下回复：

崩溃报告是否始终相同？你有堆栈痕迹吗？即以
为首的崩溃转储中的位 --------------- P R O C E S S ---------------
这是一个模糊的转储tbh。一种可能性是狡猾的RAM，因为它似乎已经在达到安全点时死亡以收集垃圾。你在盒子上做过任何硬件诊断吗？
答案 1 :(得分：1)
我同意马特的观点，这听起来像硬件问题。我已经看过你的三个崩溃报告，它们都在不同的部分都失败了。一，主要是在执行VM代码时。第二个是本机代码。第三个（在这个问题中你应该没有打开，但在这里添加），标准Java代码。
当然，如果您有多台生产机器并且问题出现在不同的生产机器上，那么我会认真考虑购买订阅并获得真正的支持。
