Question

我有一个运行64位Debian Lenny的VPS，我正在部署几个Rails 3应用程序。

我在本地没有问题，但每当Rake从命令行（或capistrano）运行时，Rake段错误和核心转储......即使Rake似乎在大多数情况下完成成功！ / p>

我花了几周试图解决这个问题，尝试安装REE，1.8.7,1.9.2-p180＆amp; 1.9.2-p290 ......所有这些都失败了。

我不确定如何从核心转储中获取任何有意义的信息......而我在谷歌上的所有搜索都没有结果。

有什么选择可以阻止这种情况发生？有没有办法阻止核心转储占用我的所有磁盘空间？！

我不确定如何从核心转储中获取任何有意义的信息......

您是否尝试过以标准方式从核心转储中获取信息？

gdb /path/to/executable /path/to/core
(gdb) where

耙子总是会出现段错误和核心转储，即使成功也是如此
