那些遇到过的问题

关于如何解决/调试JVM崩溃的最佳方法(SIGSEGV)

Phi*_*ipp 6 java jvm segmentation-fault

我真的迷路了,我不知道如何面对并解决我的问题.我有一个简单的Java代码,导致JVM崩溃:

#

我不知道如何解决这个问题.该程序非常简单,它通过Kafka接收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,程序会在900 - 1,500条消息后崩溃.所有的消息是相同的,程序不使用任何JNI的东西(据我所知,使用过的第三方库也没有使用任何JNI).

我从来没有遇到过这个问题,但是我喜欢/需要找到一种方法来解决问题所在.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!

编辑(1):有时我也得到以下错误/信息:

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提供的解决方案,因为调用jmap会导致另一个错误:"附加到核心文件的错误:无法附加到核心文件").使用VisualVM创建的threaddump导致:

崩溃报告告诉JIT编译器线程中发生了错误:

Current thread (0x00007f89e481c800):  JavaThread "C2 CompilerThread1"
Run Code Online (Sandbox Code Playgroud)

采取以下步骤来诊断编译器问题:

  1. 尝试JDK 9 EA中最新的JVM构建:https://jdk9.java.net/download/

    如果问题消失了,您可以使用此版本留或尝试找到确切的承诺,解决了这个问题,然后反向移植到JDK 8.如何反向移植修复,以及如何建立自己的HotSpot - 它是一个单独的话题,但我可以告诉你是否感兴趣.

  2. 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.

    Current CompileTask: C2: 114667 5303 4 com.sosse.time.timeseries.gson.TypeConverterHelper::deserialize (157 bytes)
    Run Code Online (Sandbox Code Playgroud)

    看起来在你的情况下,它无法编译TypeConverterHelper.deserialize().添加以下JVM选项以排除此特定方法:

    -XX:CompileCommand=exclude,com.sosse.time.timeseries.gson.TypeConverterHelper::deserialize
    Run Code Online (Sandbox Code Playgroud)

  3. 如果没有帮助,请尝试通过提供多个方法来排除更多方法-XX:CompileCommand.要找到排除使用的候选人-XX:+PrintCompilation并查看打印列表的底部.您也可以从编译中排除整个类和包,例如

    -XX:CompileCommand=exclude,com.sosse.time.timeseries.gson.*::*

-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

  5. 无论是否找到有问题的方法/优化,再次运行JVM

    -XX:+UnlockDiagnosticVMOptions -XX:+LogCompilation
    Run Code Online (Sandbox Code Playgroud)

    这将hotspot_pid1234.log使用详细的编译日志在当前目录中创建文件.

  6. 在bugreport.java.com上提交错误报告.选择

    Product/Category: HotSpot Virtual Machine (errors)
Subcategory:      J2SE Server Compiler
    Run Code Online (Sandbox Code Playgroud)

    确保包括完整hs_err_pid.log和hotspot_pid.log从第5步.如果您可以提供一个简化的自包含示例来说明问题,将会非常有帮助.

    为了加快反应,您还可以向hotspot-compiler-dev邮件列表发送消息.

它看起来像 JDK 错误JDK-6675699。根据错误报告，该错误的修复程序已向后移植到 8u74、8u81 和 8u82。

请注意（截至目前）面向最终用户的Java 下载站点提供 8u73 作为最新版本。您可以从Java 开发人员下载站点获得 8u74 。

如果更新到 8u74 不能解决问题，那么您应该将此作为错误报告提交给 Oracle。可能的诊断是您正在运行的代码导致 JIT 代码编译器在尝试编译/优化它时崩溃。这PhaseIdealLoop::idom_no_update就是表明。

JDK-6675699 针对特定的 JIT 编译器错误。很可能还有其他尚未诊断的 JIT 编译器错误。如果您提交新的错误报告，它可以帮助维护人员追踪这些错误。但是，只有在您提供足够的信息以允许他们重现您的错误时，错误报告才会对他们有用。

（当然，也有可能根本原因完全不同；例如，您的代码中的某些 3rd 方代码破坏了 JVM 数据结构，导致编译器崩溃。但如果重复出现损坏，那将是一个巨大的巧合破坏编译器……而且只有编译器。）

更新- 根据这些发行说明，您实际需要的版本是 Java SE 8u74-b32。
