在Eclipse和Tomcat（wtp）中处理webapp时，tomcat崩溃并创建一个文件：hs_err_pid20216.log
When working on a webapp in Eclipse and Tomcat (wtp) , tomcat crashes and create a file: hs_err_pid20216.log
我试图用eclipse MAT来分析文件，但MAT不能将文件识别为它可以处理的东西，我也尝试了DAT，这是同样的事情。它不会显示在打开的文件对话框中。
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.
它是什么类型的文件？
应该怎样我用它来分析它吗？
What should I use to analyze 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。
Do I have to make changes to this file so that it will be possible for these tools to parse it.

有关如何处理hs_err_pidXYZ.log文件的更多信息，请参阅@Dan Cruz回复。好奇的是，崩溃的原因是杰克逊被一个循环关系混淆（双向一对多），但这是另一个故事...
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 Jackson being confused by a cyclic relationship (bidirectional one-to-many) but this is another story...
推荐答案
这是一个HotSpot错误日志文件文本格式。
It's a HotSpot error log file in text format.
首先下载。在错误日志中搜索字符串的热点 *。cpp 文件。查看源文件以获取错误日志包含的说明。
Start by downloading the OpenJDK 6 source bundle. Search through the hotspot *.cpp files for strings in the error log. Review the source files for an explanation of what the error log contains.
例如，使用OpenJDK 7源，您可以找到 siginfo os :: print_siginfo（）方法中的c $ c>（操作系统进程信号信息）。 net / jdk7 / jdk7 / hotspot / file / 81d815b05abb / src / os / linux / vm / os_linux.cpp\"rel =noreferrer> os_linux.cpp ，在等。
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.
这是不可能的，因为需要一个堆文件，w HotSpot错误日志不是。
That would be impossible since the Eclipse Memory Analyzer requires a heap file, which the HotSpot error log is not.
