Jvm崩溃:Java运行时环境检测到致命错误

I had a tomcat crash on live server , which generated hs_err_pid file .In this there is a Problematic frame -> _wordcopy_fwd_dest_aligned+0x54. I searched in all similar cases of jvm crash but couldn't find whats the meaning of this problematic frame.Any suggestions ?

我在live服务器上遇到了tomcat崩溃，它生成了hs_err_pid文件，这是一个有问题的框架——> _wordcopy_fwd_dest_align +0x54。我搜索了所有类似的jvm崩溃案例，但找不到这个问题框架的含义。有什么建议吗?

2 个解决方案

#1

1. Crash you observed is not a java issue it is redhat issue "https://bugzilla.redhat.com/show_bug.cgi?id=546158"
2. 您观察到的崩溃不是java问题，而是redhat发出的“https://bugzilla.redhat.com/show_bug.cgi?id=546158”
3. What is Problematic Frame: It is the top frame resulted in the crash, in your case it is native frame (C) resulted in libC.so file. Please find more details here
4. 有问题的框架:它是顶部框架导致了崩溃，在你的例子中它是本机框架(C)导致了libC。所以文件。详情请点击这里

#2

There are several possibilities, here. But unless you are using any native libraries (e.g. tcnative), the fault lies completely outside the application (including Tomcat here as part of "the application"). Nothing the application can do should cause the JVM to crash.

这里有几种可能性。但是，除非您正在使用任何本机库(例如tcnative)，否则错误完全位于应用程序之外(包括作为“应用程序”一部分的Tomcat)。应用程序所能做的任何事情都不应该导致JVM崩溃。

1. There is a bug in a native library you are using
2. 您正在使用的本机库中有一个错误
3. There is a bug in the JVM
4. JVM中有一个错误
5. There is a bug in libc
6. libc里有个虫子
7. You have a hardware error
8. 你有一个硬件错误

I think that #1 is the most likely if you actually have any native components.

我认为如果您确实有任何本机组件，那么#1是最有可能的。

I think #4 is the most likely if you do not have any native components. Every time I've ever seen a SIGBUS it has turned out to be a problem with the underlying hardware. If possible, take that machine out of service and run memtest86+ (or equivalent for your architecture) on the machine. It will exercise the memory, CPU, the system bus to see if working them constantly can expose a problem.

我认为如果您没有任何本机组件，那么#4是最可能的。每次我看到SIGBUS，都发现底层硬件出了问题。如果可能的话，将该机器停用，并在机器上运行testmem86 +(或与您的体系结构等效)。它将对内存、CPU和系统总线进行测试，以查看是否持续运行它们会暴露问题。

If your system passes 2 tests of memtest86+, I'd say that you have more likely found a bug in the JVM (unlikely) or in libc (even less likely). In either of these cases, upgrade everything to the latest versions and re-try.

如果您的系统通过了两次memtest86+测试，那么我认为您更可能在JVM(不太可能)或libc(更不可能)中发现bug。在这两种情况下，将所有内容升级到最新版本并重新尝试。
