hs_err_prd.log日志分析
java程序运行的时候，突然JVM发生错误导致崩溃时，会生成一个hs_err_pid_xxx.log这样的文件，该文件包含了导致 JVM crash 的重要信息，我们可以通过分析该文件定位到导致 JVM Crash 的原因，从而修复保证系统稳定，默认该文件出生在项目得根目录。
这个文件主要包含如下内容：
- 日志头信息
- crash 的线程信息
- 所有线程信息
- 安全点和锁信息
- 堆信息
- 本地代码缓存
- 编译事件
- gc 相关时间
- 逆优化
- 重新定义类
- 内部异常信息
- jvm 内存映射
- jvm 启动参数
- 服务器信息
一、日志头文件
#
# There is insufficient memory for the Java Runtime Environment to continue.
# Native memory allocation (malloc) failed to allocate 32744 bytes for ChunkPool::allocate
# Possible reasons:
# The system is out of physical RAM or swap space
# The process is running with CompressedOops enabled, and the Java Heap may be blocking the growth of the native heap
# Possible solutions:
# Reduce memory load on the system
# Increase physical memory or swap space
# Check if swap backing store is full
# Decrease Java heap size (-Xmx/-Xms)
# Decrease number of Java threads
# Decrease Java thread stack sizes (-Xss)
# Set larger code cache with -XX:ReservedCodeCacheSize=
# JVM is running with Zero Based Compressed Oops mode in which the Java heap is
# placed in the first 32GB address space. The Java Heap base address is the
# maximum limit for the native heap growth. Please use -XX:HeapBaseMinAddress
# to set the Java Heap base and to place the Java Heap above 32GB virtual address.
# This output file may be truncated or incomplete.
#
# Out of Memory Error (allocation.cpp:272), pid=16756, tid=0x0000000000006b78
#
# JRE version: Java(TM) SE Runtime Environment (8.0_231-b11) (build 1.8.0_231-b11)
# Java VM: Java HotSpot(TM) 64-Bit Server VM (25.231-b11 mixed mode windows-amd64 compressed oops)
# Failed to write core dump. Minidumps are not enabled by default on client versions of Windows
#
翻译过来的意思大概就是：
没有足够的内存，Java运行时环境无法继续。本机内存分配（malloc）无法为ChunkPool :: allocate分配32744个字节可能的原因：系统没有物理RAM或交换空间该进程正在启用CompressedOops的情况下运行，并且Java Heap可能阻止了本机堆的增长可能的解决方案：
减少系统上的内存负载增加物理内存或交换内存检查交换后备存储是否已满减小Java堆大小（-Xmx / -Xms）减小Java线程数减小Java线程堆栈大小（-Xss）设置较大的代码-XX：ReservedCodeCacheSize =
进行高速缓存JVM以基于零的压缩Oops模式运行，在该模式下，Java堆位于前32GB地址空间中。 Java堆基址是本机堆增长的最大限制。请使用-XX：HeapBaseMinAddress设置Java Heap基础并将Java Heap放置在32GB以上的虚拟地址上。
该输出文件可能被截断或不完整。内存不足错误（allocation.cpp：272），pid = 16756，tid = 0x0000000000006b78
JRE版本：Java（TM）SE运行时环境（8.0_231-b11）（内部版本1.8.0_231-b11）
Java VM：Java HotSpot（TM） ）64位服务器VM（25.231-b11混合模式Windows-amd64压缩的oops）
无法写入核心转储。默认情况下，在Windows客户端版本上不启用小型转储
这段信息简述了发生异常的信息，是服务器内存不足，除此之外，JVM 自身的 bug，应用程序错误，JVM 参数，JNI 调用错误，版本信息和配置信息等也会导致JVM Crash。
Out of Memory Error (allocation.cpp:272), pid=16756, tid=0x0000000000006b78- pid=16756 进程号
- tid=0x0000000000006b78 线程号
二、crash 的线程信息
--------------- T H R E A D ---------------

Current CompileTask:

线程信息
Current thread (0x0000000001e94800): JavaThread "pool-1-thread-2" [_thread_in_native, id=30111, stack(0x00007f3d567e5000,0x00007f3d568e6000)]- 0x0000000001e94800：出错的线程指针
- JavaThread：线程类型，线程可能还会有以下：
- JavaThread：Java线程
- VMThread : JVM 的内部线程
- CompilerThread：用来调用JITing，实时编译装卸class 。 通常，jvm会启动多个线程来处理这部分工作，线程名称后面的数字也会累加，例如：CompilerThread1
- GCTaskThread：执行gc的线程
- WatcherThread：JVM 周期性任务调度的线程，是一个单例对象
- ConcurrentMarkSweepThread：jvm在进行CMS GC的时候，会创建一个该线程去进行GC，该线程被创建的同时会创建一个SurrogateLockerThread（简称SLT）线程并且启动它，SLT启动之后，处于等待阶段。CMST开始GC时，会发一个消息给SLT让它去获取Java层Reference对象的全局锁：Lock
- pool-1-thread-2：线程名称
- _thread_in_native：当前线程状态
- _thread_in_native：线程当前状态，状态枚举包括：
- _thread_uninitialized：线程还没有创建，它只在内存原因崩溃的时候才出现
- _thread_new：线程已经被创建，但是还没有启动
- _thread_in_native：线程正在执行本地代码，一般这种情况很可能是本地代码有问题
- _thread_in_vm：线程正在执行虚拟机代码
- _thread_in_Java：线程正在执行解释或者编译后的Java代码
- _thread_blocked：线程处于阻塞状态
- …_trans：以_trans结尾，线程正处于要切换到其它状态的中间状态
- id=30111 ：线程id
- stack(0x00007f3d567e5000,0x00007f3d568e6000)：栈区间

四、安全点和锁信息
VM state:not at safepoint (normal execution)
VM Mutex/Monitor currently owned by a thread: None虚拟机状态：
- not at safepoint 表示正常运行。其余状态：
- at safepoint：所有线程都因为虚拟机等待状态而阻塞，等待一个虚拟机操作完成；
- synchronizing：一个特殊的虚拟机操作，要求虚拟机内的其它线程保持等待状态。
虚拟机的 Mutex 和 Monito r目前没有被线程持有。Mutex 是虚拟机内部的锁，而 Monitor 则关联到了 Java 对象。
五、堆信息
