解决/调试JVM崩溃(SIGSEGV)的最佳方法 [英] Best way on how to solve/debug JVM crash (SIGSEGV)
本文介绍了解决/调试JVM崩溃(SIGSEGV)的最佳方法的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我真的迷路了，我不知道该如何面对和解决我的问题.我有一段简单的Java代码，导致JVM崩溃:
I'm really lost and I don't know how to face and solve my problem. I have a piece of simple Java Code, which leads to a JVM crash:
#
# A fatal error has been detected by the Java Runtime Environment:
#
# SIGSEGV (0xb) at pc=0x00000001057ce9d4, pid=10727, tid=18947
#
# JRE version: Java(TM) SE Runtime Environment (8.0_73-b02) (build 1.8.0_73-b02)
# Java VM: Java HotSpot(TM) 64-Bit Server VM (25.73-b02 mixed mode bsd-amd64 compressed oops)
# Problematic frame:
# V [libjvm.dylib+0x3ce9d4] PhaseIdealLoop::idom_no_update(Node*) const+0x12
#
# Failed to write core dump. Core dumps have been disabled. To enable core dumping, try "ulimit -c unlimited" before starting Java again

Current thread (0x00007feeef003800): JavaThread "C2 CompilerThread0" daemon [_thread_in_native, id=18947, stack(0x0000700000ec4000,0x0000700000fc4000)]
siginfo: si_signo: 11 (SIGSEGV), si_code: 1 (SEGV_MAPERR), si_addr: 0x0000000000000008
我不知道如何解决问题.该程序非常简单，它通过Kafka接收一条消息，并根据收到的消息触发任务.如果我添加两个不同的任务，该程序将在900-1,500条消息后崩溃.所有消息都是相同的，并且程序不使用任何JNI东西(据我所知，使用过的第三方库也不使用任何JNI).
I have no idea on how to solve the problem. The program is pretty simple, it receives a message through Kafka and triggers tasks based on the message received. If I add two different tasks, the program crashes after 900 - 1,500 messages. All of the messages are the same and the program does not use any JNI stuff (the used 3rd party libraries don't use any JNI as well, as far as I'm informed).
我从来没有遇到过这个问题，但是我希望/需要找到一种方法来弄清楚问题是什么.我已经使用了其他版本的JVM(Java 8.0_66、8.0_73-b02和8.0_74-b02).那我该怎么办?非常感谢！
I never faced this problem, but I'd love/need to find a way on how to figure out what the problem is. I already used other versions of the JVM (Java 8.0_66, 8.0_73-b02, and 8.0_74-b02). So what can I do? Thank you so much!
编辑(1):有时我还会收到以下错误/信息:
EDIT (1): Sometimes I also get the following error/info:
...

# Problematic frame:
# V [libjvm.dylib+0x3ce9d4]
...
编辑(2):我将Java版本更新为8.0_74.错误仍然存在:(.
EDIT (2): I updated my Java version to 8.0_74. The error is still there :(.

编辑(3):核心转储
因此，最后我创建了一个核心转储并将其加载到Java VisualVM中(我无法使用DROY提出的解决方案，因为调用jmap会导致另一个错误:附加到核心文件时出错:无法附加到核心文件中" ).使用VisualVM创建的线程转储会导致:
So finally I created a core dump and loaded it into Java VisualVM (I could not use the solution presented by DROY because calling jmap lead to another error: "Error attaching to core file: Can't attach to the core file"). The threaddump created with VisualVM results in:

推荐答案
崩溃报告指出JIT编译器线程中已发生错误:
The crash report tells the error has happened in JIT compiler thread:
Current thread (0x00007f89e481c800): JavaThread "C2 CompilerThread1"
采取以下步骤来诊断编译器问题:
Take the following steps do diagnose compiler problems:
-
尝试在JDK 9 EA中使用最新的JVM构建: https://jdk9.java.净/下载/
如果问题消失了，则可以使用此版本，也可以尝试找到可以解决问题的确切提交，然后将其反向移植到JDK8.如何反向移植修补程序以及如何自己构建HotSpot-这是一个单独的主题，但我可以告诉您是否有兴趣.
If the problem disappears, you can either stay with this version or try to locate the exact commit that solves the issue and then backport it to JDK 8. How to backport fixes and how to build HotSpot yourself - it's a separate topic, but I can tell if you're interested.
如果问题仍然存在，请尝试查找有问题的方法并将其从编译中排除.
If the problem persists, try to find a problematic method and exclude it from compilation.
Current CompileTask: C2: 114667 5303 4 com.sosse.time.timeseries.gson.TypeConverterHelper::deserialize (157 bytes)
看起来像您的情况，它编译TypeConverterHelper.deserialize()失败.添加以下JVM选项以排除此特定方法:
Looks like in your case it fails compiling TypeConverterHelper.deserialize(). Add the following JVM option to exclude this particular method:
-XX:CompileCommand=exclude,com.sosse.time.timeseries.gson.TypeConverterHelper::deserialize
如果这样做没有帮助，请尝试通过提供多个-XX:CompileCommand排除更多方法.要查找排除的候选者，请使用-XX:+PrintCompilation并查看打印列表的底部.您还可以从编译中排除整个类和程序包，例如
If it does not help, try to exclude more methods by providing multiple -XX:CompileCommand. To find candidates to exclude use -XX:+PrintCompilation and look at the bottom of the printed list. You can also exclude the whole classes and packages from compilation, e.g.
-XX:CompileCommand=exclude,com.sosse.time.timeseries.gson.*::*
尝试逐个禁用某些编译器优化.可以尝试的一些选项是:
Try to disable certain compiler optimizations one by one. Some options to try are:
-XX:-DoEscapeAnalysis
-XX:LoopUnrollLimit=0
-XX:-PartialPeelLoop
-XX:-UseLoopPredicate
-XX:-LoopUnswitching
-XX:-ReassociateInvariants
-XX:MaxInlineLevel=1
-XX:-IncrementalInline
-XX:-RangeCheckElimination
-XX:-EliminateAllocations
-XX:-UseTypeProfile
-XX:AliasLevel=0
是否找到有问题的方法/优化，请再次使用
Whether the problematic method/optimization is found or not, run JVM again with
-XX:+UnlockDiagnosticVMOptions -XX:+LogCompilation
这将在当前目录中创建带有详细编译日志的hotspot_pid1234.log文件.
This will create hotspot_pid1234.log file in the current directory with detailed compilation log.
通过 bugreport.java.com 提交错误报告.选择
Submit the bug report at bugreport.java.com. Select
Product/Category: HotSpot Virtual Machine (errors)
Subcategory: J2SE Server Compiler
请确保在第5步中包含完整的hs_err_pid.log和hotspot_pid.log.如果您可以提供一个简化的独立示例来说明问题，那将非常有帮助.
Make sure to include full hs_err_pid.log and hotspot_pid.log from step 5. It would be very helpful if you could provide a reduced self-contained example that demonstrates the problem.
为了更快地做出反应，您还可以将消息发布到 hotspot-compiler -dev 邮件列表.
For a faster reaction you may also post a message to hotspot-compiler-dev mailing list.
