Question

我在debian linux上执行一个控制器，它在无限循环中执行一个功能。与此同时，我使用Rufus Scheduler来安排一个功能，该功能在特定时间后运行1分钟。一旦函数在Rufus中正确执行，我就会收到以下错误

    /usr/local/rvm/gems/ruby-2.1.0/gems/rufus-scheduler-3.0.4/lib/rufus/scheduler.rb:505:   [BUG] Segmentation fault at 0x00000000000000

Answer 1

这是一个异常，它是从本机库抛出的，而不是Ruby本身。看起来根本原因可能出在您正在使用的tiny_tds gem中：

/usr/local/rvm/gems/ruby-2.1.0/extensions/x86_64-linux/2.1.0/tiny_tds-0.6.1/tiny_tds/tiny_tds.so(+0x44f1) [0x2b1907ff24f1] result.c:89

您是否尝试升级到更高版本的tiny_tds以查看问题是否仍然存在？

编辑：我看到它是最新版本;也许用tiny_tds维护者提出这个问题 - 见https://github.com/rails-sqlserver/tiny_tds

Ruby代码在Rufus调度程序中抛出异常
