我们有一个基于 Jboss 构建的 Web 应用程序，已经投入生产多年；在过去的 18 个月里，它从未下降过。然而，最近两天，jvm崩溃了4次。
当 JVM 崩溃时，我们会收到一份我正在努力解读的错误报告。我看过其他几个崩溃报告（在这个网站和其他网站上），但没有一个与我们的完全一样；因为我是阅读它们的新手，所以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...我将发布其中 2 份（为了简洁起见，图书馆除外），以防有助于诊断问题。这 4 个看起来都不完全相同。我只发布 2 个，因为正文有 30000 个字符的限制。

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. 在 Jboss 上打开调试，看看是否可以在 JVM 崩溃之前捕获更多信息。
如果您有任何建议，非常感谢！
从昨晚开始更新
所以，服务器运行了几天……然后第五次再次崩溃。我在此处的新报告中添加了一个新问题：https://stackoverflow.com/questions/6005976/jboss-hotspot-jvm-crashing-again
