我真的迷路了,我不知道如何面对并解决我的问题。我有一段简单的Java代码,导致JVM崩溃:
#

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)。
我从未遇到过这个问题,但我喜欢/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?非常感谢你!
编辑(1):有时我也会收到以下错误/信息:
...
# JRE version: Java(TM) SE Runtime Environment (8.0_73-b02) (build 1.8.0_73-b02)

...
编辑(2):我将Java版本更新为8.0_74。错误仍然存在:(。

编辑(3):核心转储
所以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编译器线程中发生错误:
Current thread (0x00007f89e481c800): JavaThread "C2 CompilerThread1"
采取以下步骤来诊断编译器问题:
尝试JDK 9 EA中提供的最新JVM版本:https://jdk9.java.net/download/
如果问题消失,你可以继续使用这个版本,或者尝试找到解决问题的确切提交,然后将其反向移植到JDK 8.如何回溯修复以及如何自己构建HotSpot - 它是&#39; sa单独的主题,但我可以告诉您是否感兴趣。
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)
在您的情况下,它似乎无法编译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
如果没有帮助,请尝试通过提供多个-XX:CompileCommand
来排除更多方法。要查找要排除使用-XX:+PrintCompilation
的候选项并查看打印列表的底部。您还可以从编译中排除整个类和包,例如
-XX:CompileCommand=exclude,com.sosse.time.timeseries.gson.*::*
尝试逐个禁用某些编译器优化。一些尝试的选项是:
-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,再次使用
运行JVM-XX:+UnlockDiagnosticVMOptions -XX:+LogCompilation
这将使用详细的编译日志在当前目录中创建hotspot_pid1234.log
文件。
在bugreport.java.com提交错误报告。选择
Product/Category: HotSpot Virtual Machine (errors)
Subcategory: J2SE Server Compiler
请务必在第5步中添加完整的hs_err_pid.log
和hotspot_pid.log
。如果您能提供一个展示问题的简化自包含示例,那将非常有用。
为了加快反应,您还可以向hotspot-compiler-dev邮件列表发送消息。
答案 1 :(得分:4)
看起来像JDK bug JDK-6675699。根据错误报告,该bug的修复程序已被移植到8u74,8u81和8u82。
请注意(截至目前),专注于最终用户Java Download Site提供8u73作为最新版本。您可以从Java Developer Download Site获得8u74。
如果更新到8u74并未解决问题,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导致JIT代码编译器在尝试编译/优化它时崩溃的代码。这是PhaseIdealLoop::idom_no_update
表示的内容。
JDK-6675699用于特定的JIT编译器错误。可能还有其他未被诊断的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,如果您能够提供足够的信息以允许它们重现您的错误,则错误报告仅对它们有用。
(当然,根本原因也可能是完全不同的;例如,代码第三方代码中的某些东西正在破坏导致编译器崩溃的JVM数据结构。但这对于腐败重复打破编译器...只有编译器。)
更新 - 根据这些Release Notes,您实际需要的版本是Java SE 8u74-b32。
答案 2 :(得分:1)
我认为你应该花一些时间来分析核心。
细分错误
这有几个可能的原因。 JVM本身或包中可能存在错误(其中一些是用C或C ++编写的)。这也可能是由于错误配置,其中不兼容的组件一起使用。
根据经验,JVM错误最不可能发生。虽然@Stephen认为这是可能的情况。
如果你在崩溃点捕获堆栈跟踪,这可能会为你提供一些关于崩溃发生在何处的线索。
首先,我看到你需要配置ulimit -c unlimited,以便你可以将核心文件存储到磁盘。
分析核心档案
完成后,您应该使用以下方法分析核心。
要转换文件,请使用命令行工具jmap。
jmap -dump:format=b,file=dump.hprof /usr/bin/java core_file
其中:
dump.hprof是您要创建的hprof文件的名称
/ usr / bin / java是生成核心转储的java二进制版本的路径
