你的java程序，突然之间，崩溃掉了，并且生成了core dump文件（内核dump文件）
这个时候，你该怎么办呢 ？
在本文档中，你将会知道怎样，对java的core dump文件进行分析，知道是什么原因导致的java程序崩溃、宕机。
方法 1：hs_err_pid日志文件
当jvm发生严重的故障的时候，会生成一个错误的日志文件，叫做hs_err_pidXXX.log文件
这个文件的开头部分，包含了引起崩溃的原因，比如：
$ head hs_err_pid21178.log # # A fatal error has been detected by the Java Runtime Environment: # # SIGSEGV (0xb) at pc=0x0000002b1d00075c, pid=21178, tid=1076017504 # # JRE version: 6.0_21-b06 # Java VM: Java HotSpot(TM) 64-Bit Server VM (17.0-b16 mixed mode linux-amd64 ) # Problematic frame: # C [libnativelib.so+0x75c] bar+0x10 #
同时包括相关的堆栈信息
Stack: [0x000000004012b000,0x000000004022c000], sp=0x000000004022aac0, free space=3fe0000000000000018k Native frames: (J=compiled Java code, j=interpreted, Vv=VM code, C=native code) C [libnativelib.so+0x75c] bar+0x10 C [libnativelib.so+0x772] foo+0xe C [libnativelib.so+0x78e] Java_CoreDumper_core+0x1a j CoreDumper.core()V+0 j CoreDumper.main([Ljava/lang/String;)V+7 v ~StubRoutines::call_stub V [libjvm.so+0x3e756d]
方法 2：调试一个java core dump文件
在某些情况下，JVM程序崩溃时，并没有生成hs_err_pid错误日志文件，这个时候，需要分析生成的core dump文件
linux 操作系统，一般在以下的目录中生成core dump文件
[root@yks coredump]# pwd /var/lib/systemd/coredump [root@yks coredump]# ls core.java.0.13f526e86d594c84b8d1e81350652513.1002497.1684925692000000000000.lz4 core.java.0.13f526e86d594c84b8d1e81350652513.3021304.1684991750000000000000.lz4 core.java.0.13f526e86d594c84b8d1e81350652513.886489.1684924527000000000000.lz4 core.java.0.13f526e86d594c84b8d1e81350652513.1033031.1684925966000000000000.lz4 core.java.0.13f526e86d594c84b8d1e81350652513.486294.1684840068000000000000.lz4 core.java.0.13f526e86d594c84b8d1e81350652513.906130.1685005192000000000000.lz4 core.java.0.13f526e86d594c84b8d1e81350652513.1124818.1684926927000000000000.lz4 core.java.0.13f526e86d594c84b8d1e81350652513.719506.1684845137000000000000.lz4 core.java.0.13f526e86d594c84b8d1e81350652513.911941.1684924787000000000000.lz4 core.java.0.13f526e86d594c84b8d1e81350652513.1218294.1684928407000000000000.lz4 core.java.0.13f526e86d594c84b8d1e81350652513.821657.1684923992000000000000.lz4 core.java.0.13f526e86d594c84b8d1e81350652513.979175.1684925431000000000000.lz4 [root@yks coredump]#
通过以下的几种工具，你可以对core dump文件进行调试
1、gdb
GNU Debugger (gdb)，可以对core文件进行检查，找出当程序崩溃的时候，程序正在做什么
$ gdb $JAVA_HOME/bin/java /var/tmp/cores/java.14015.146385.core (gdb) where #0 0x0000002a959bd26d in raise () from /lib64/tls/libc.so.6 #1 0x0000002a959bea6e in abort () from /lib64/tls/libc.so.6 #2 0x0000002b1cecf799 in bar () from libnativelib.so #3 0x0000002b1cecf7a7 in foo () from libnativelib.so #4 0x0000002b1cecf7c3 in Java_CoreDumper_core () from libnativelib.so #5 0x0000002a971aac88 in ?? () #6 0x0000000040113800 in ?? () #7 0x0000002a9719fa42 in ?? () #8 0x000000004022ab10 in ?? () #9 0x0000002a9a4d5488 in ?? () #10 0x000000004022ab70 in ?? () #11 0x0000002a9a4d59c8 in ?? () #12 0x0000000000000000 in ?? ()
where命令打印堆栈信息，知道是哪个程序引起的宕机。
2、jstack
jstack可以打印core dump文件的线程堆栈信息

你可以通过这些堆栈信息，分析当时程序在做什么。
3、jmap
使用jmap工具检查core文件，打印出内存的映射或者堆栈内存的详细信息

注意：如果你的java进程运行在容器里面，然后生成了core dump文件，在操作系统的目录里面，建议，将core dump文件拷贝到容器里面，然后进行分析。
大多数的基础镜像里面是没有gdb工具的，可以考虑增加，或者使用jmap、jstack来分析。
