java 如何分析JVM崩溃文件hs_err_pidXYZ.log

How to analyze JVM crash file hs_err_pidXYZ.log

提问by redochka

When working on a webapp in Eclipse and Tomcat (wtp) , tomcat crashes and create a file: hs_err_pid20216.log

在 Eclipse 和 Tomcat (wtp) 中处理 webapp 时，tomcat 崩溃并创建一个文件：hs_err_pid20216.log

I tried to use eclipse MAT to analyse the file but MAT doesn't recognize the file as something it can handle, I tried also DAT and it was the same thing. It won't show in the open file dialog.

我尝试使用 eclipse MAT 来分析文件，但 MAT 无法将文件识别为它可以处理的内容，我也尝试了 DAT，结果是一样的。它不会显示在打开文件对话框中。

What kind of file is it?

它是什么类型的文件？

What should I use to analyze it?

Do I have to make changes to this file so that it will be possible for these tools to parse it.

我是否必须对此文件进行更改，以便这些工具可以解析它。

The log file is available as a GitHub gist

日志文件作为GitHub 要点提供

See @Dan Cruz reply for more information on how to deal with hs_err_pidXYZ.log file. For curious, the cause of the crash was Hymanson being confused by a cyclic relationship (bidirectional one-to-many) but this is another story...

有关如何处理 hs_err_pidXYZ.log 文件的更多信息，请参阅 @Dan Cruz 回复。出于好奇，崩溃的原因是Hyman逊被循环关系（双向一​​对多）弄糊涂了，但这是另一个故事......

It's a HotSpot error log file in text format.

这是一个文本格式的 HotSpot 错误日志文件。

What should I use to analyze it?

我应该用什么来分析它？

Start by downloading the OpenJDK 6 source bundle. Search through the hotspot *.cppfiles for strings in the error log. Review the source files for an explanation of what the error log contains.

首先下载OpenJDK 6 源包。在热点*.cpp文件中搜索错误日志中的字符串。查看源文件以了解错误日志包含的内容。

For example, using OpenJDK 7 sources, you can find siginfo(the operating system process signal information) in the os::print_siginfo()method of os_linux.cpp, Registers(the CPU registers' values) in the os::print_context()method of os_linux_x86.cpp, etc.

例如，使用OpenJDK 7个的来源，可以发现siginfo在（操作系统进程信号信息）os::print_siginfo()的方法os_linux.cpp，Registers在（在CPU寄存器值）os::print_context()的方法os_linux_x86.cpp等。

Do I have to make changes to this file sothat it will be possible for these tools to parse it.

That would be impossible since the Eclipse Memory Analyzerrequires a heap file, which the HotSpot error log is not.

这是不可能的，因为Eclipse Memory Analyzer需要一个堆文件，而 HotSpot 错误日志则不需要。

It's a text file. Open it in an editor and try to understand what it means.

这是一个文本文件。在编辑器中打开它并尝试理解它的含义。
