hs_err_prd.log日志分析

发布于2020-11-19 20:51     阅读(765)     评论(0)     点赞(8)     收藏(4)


 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

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:

  1. 减少系统上的内存负载
  2. 增加物理内存或交换内存
  3. 检查交换后备存储是否已满
  4. 减小Java堆大小(-Xmx / -Xms)
  5. 减小Java线程数减小Java线程堆栈大小(-Xss)
  6. 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
复制代码
  • pid=16756 进程号
  • tid=0x0000000000006b78 线程号

二、crash 的线程信息

---------------  T H R E A D  ---------------

Current thread (0x000000001fd37800):  JavaThread "C2 CompilerThread0" daemon [_thread_in_native, id=27512, stack(0x0000000020170000,0x0000000020270000)]

Stack: [0x0000000020170000,0x0000000020270000]
[error occurred during error reporting (printing stack bounds), id 0xc0000005]

Native frames: (J=compiled Java code, j=interpreted, Vv=VM code, C=native code)


Current CompileTask:
C2:  19813 10229       4       java.net.URLClassLoader$1::run (5 bytes)

复制代码

线程信息

Current thread (0x0000000001e94800):  JavaThread "pool-1-thread-2" [_thread_in_native, id=30111, stack(0x00007f3d567e5000,0x00007f3d568e6000)]
复制代码
  • 0x0000000001e94800:出错的线程指针
  • JavaThread:线程类型,线程可能还会有以下:
  1. JavaThread:Java线程
  2. VMThread : JVM 的内部线程
  3. 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
  4. GCTaskThread:执行gc的线程
  5. WatcherThread:JVM 周期性任务调度的线程,是一个单例对象
  6. 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
  1. _thread_in_native:线程当前状态,状态枚举包括:
  2. _thread_uninitialized:线程还没有创建,它只在内存原因崩溃的时候才出现
  3. _thread_new:线程已经被创建,但是还没有启动
  4. _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
  5. _thread_in_vm:线程正在执行虚拟机代码
  6. _thread_in_Java:线程正在执行解释或者编译后的Java代码
  7. _thread_blocked:线程处于阻塞状态
  8. …_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

三、线程信息

如上信息,线程阻塞

四、安全点和锁信息

VM state:not at safepoint (normal execution)

VM Mutex/Monitor currently owned by a thread: None
复制代码

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
