如何找出问题的根源？我看到创建了一个大约2MB核心转储的“core-java-2951-1384969911”文件。我真的需要调试核心转储吗？如果是的话，我该怎么做？

尝试使用vm标志运行“-XX：+ PrintCommandLineFlags”请参阅http://openjdk.5641.n7.nabble.com/Bug-720-New-Error-caught-unhandled-signal-11-tomcat6-arm -debian-linux-td28451.html – vandale

由于SIG 11是一个seg故障，它发生在os_linux_zero.cpp：270中，它可能是一个JVM错误。你可以尝试使用不同的JRE版本运行吗？ – Bizmarck

由于核心转储只是正在运行的进程数据的原始转储，我要做的一件事就是将其转换为堆转储。要做到这一点，你可以用JMAP：

jmap -heap:format=b <java-executable> <core-file>

根据您的核心文件的大小，现在可能是一个好时机饮料，去吃午饭，或者甚至赶上你的电影。 （我已经看到这个命令从20分钟到一个半小时）。确保参数指向实际创建核心转储的java可执行文件。确保从同一版本的java运行jmap命令可能也是最安全的。 （jmap是相当古老的，早在Java 1.4.2中就附带了jdk）。

一旦这个命令完成，你应该有一个heap.bin文件，可以用jhat工具浏览。 （他们应该可以使用新的JVisualVM工具查看，但出于某种原因，该工具在加载这些文件时似乎失败了。）该工具不像jmap（jhat从1.6版本开始随JDK提供）那么旧，但是因为我们现在有一个堆文件而不是原始核心转储，我们可以使用随新JDK分发的jhat。既然你是在Java 6无论如何，你将被罚款：

jhat -J-Xmx1024M heap.bin

再次，这取决于堆文件的大小，该命令可能需要的时间和内存了不少。你可能不得不碰到“1024”的说法。您甚至可能需要在服务器（而不是本地计算机）上运行它，以便绕过Java在Windows上施加的2 GB堆限制。有时从核心生成的堆文件会导致jhat生成大量错误，因此您可能需要将标准输出重定向到文件。最终，jhat进程将完成读取文件并开始在端口7000上进行侦听。然后，您可以将Web浏览器指向正在运行的计算机（不要忘记将“：7000”添加到主机名）并开始浏览在JVM崩溃时堆上的对象。

更新：自从我上次运行JMap工具以来，参数可能已经发生了变化。我只是试图再次运行它，它好像我不得不使用：

jmap -dump:live,format=b,file=heap.bin <java-executable> <core-file>

如果一个命令不为你工作，你可能想尝试其他。

嗨，谢谢。我将jmap下载到windows机器上。同时，我将javatest.jar（可执行文件）和嵌入式框上生成的coredump文件复制到JMAP目录。我执行了下面的“C：\ Users \ cfd783 \ Desktop \ JMap-1.3> jmap.jar -heap：format = b javaTest.jar core-java-2951-1384969911”。它打开弹出窗口，显示“无法找到映射文件-heap：format = b”的错误消息。我在这里错过了什么吗？ – user1867459

您需要确保您正在运行的jmap的版本与生成核心文件的JDK完全对应。因此，使用Windows版本映射Linux核心可能无效。 JMap应该包含在你的Linux机器上的JDK安装中，所以你不需要下载任何东西。 （但是，如果你这样做，绝对确保你的版本与你的确切的JDK一起提供。） –

另外，我想补充一点，jhat会告诉你很多好的信息，在崩溃的时候在堆上浏览对象，并且给你一个当时正在发生的事情的好主意，但它会最可能仍然很难准确查明问题。这些东西可能很难找到。 –
