无法写入核心转储.核心转储已被禁用 [英] Failed to write core dump. Core dumps have been disabled

问题描述

我一直在从事一个视觉项目，并在 JNI 的 Java 中使用了一些 C++ 库.

I've been working on a vision project and using some C++ libraries in Java by JNI.

操作系统:Ubuntu 12.04

在我的项目中，我使用 boost 库来生成随机数.但有时我会遇到如下异常:

In my project, I'm using boost library to generate random number. But sometimes I get an exception as follows:

Core dum140002367330048 also had an error]
#

# Failed to write core dump. Core dumps have been disabled. To enable core dumping, try "ulimit -c unlimited" before starting Java again

当我在 StackOverflow 上搜索这个时，我发现了一些与 IDE (Eclipse) 相关的问题.该应用程序独立于 IDE.因此，解决方案也必须独立于 IDE.有什么想法吗?

When I searched for this on StackOverflow, I found some issues related to the IDE (Eclipse). The application is independent of the IDE. So, the solution must be independent from the IDE, too. Any ideas?

推荐答案

我遇到了同样的问题.

因为，错误本身表明 -

As, the error itself suggests -

无法写入核心转储.核心转储已被禁用.要启用核心转储，请在再次启动 Java 之前尝试 ulimit -c unlimited

Failed to write core dump. Core dumps have been disabled. To enable core dumping, try ulimit -c unlimited before starting Java again

ulimit 获取和设置用户限制.有关 ulimit 的更多信息，请执行 -

ulimit gets and sets user limits. For more info on ulimit do -

man ulimit

所以，打开一个终端并运行 -

So, open a terminal and run -

ulimit -c unlimited

这应该可以解决问题.要检查更改是否成功，请运行 -

This should solve the problem. To check if the change was successful, run -

ulimit -c -l

这应该给你一个输出如下 -

This should give you an output as follows -

core file size          (blocks, -c) unlimited
max locked memory       (kbytes, -l) 64
