如何诊断和防止JVM崩溃？ [英] How should I diagnose and prevent JVM crashes?

问题描述

当我遇到JVM崩溃时，我应该怎么做（作为一个不知道JVM内部的Java程序员）？

What should I (as a Java programmer who doesn't know anything about JVM internals) do when I come across a JVM crash?

你产生一个可重现的测试用例？我应该在Sun（或IBM的）错误数据库中搜索什么？我可以从生成的日志文件中获取什么信息（例如 hs_err_pidXYZ.log ）？

In particular, how would you produce a reproducible test case? What should I be searching for in Sun's (or IBM's) bug database? What information can I get from the log files produced (e.g. hs_err_pidXYZ.log)?

推荐答案

如果崩溃只出现一个特定计算机，请运行 memtest 。我看到反复发生的JVM崩溃只有两次，在这两种情况下，罪魁祸首是一个硬件问题，即错误的RAM。

If the crashes occur only one one specific machine, run memtest. I've seen recurring JVM crashes only two times, and in both cases the culprit turned out to be a hardware problem, namely faulty RAM.
