java - JVM 在 6.0_26-b03 中崩溃

Question

我们的生产服务器崩溃了两次，其中一个类中的框架有问题。我们无法重现此问题，也未在任何其他环境中看到它。什么会导致这种情况？

Answer 1

What can cause this?

原因很可能是您的应用程序正在使用的某些 native 代码库中的错误，或者是 JVM 错误。

在前一种情况下，您需要温习 native 代码调试技能。 (你知道，使用 gdb 和它的同类。)

在后一种情况下，升级到更新的 JVM 补丁级别可能会有所帮助。或者您可以尝试扫描发行说明的“已修复错误”部分以了解以后的 JVM 发行版。或者您可以通过 Oracle 的 Java Bug 数据库进行搜索(虽然我没有跳出有希望的搜索词......)
