Ruby 代码在 Rufus 调度程序中抛出异常

Question

我正在 debian linux 上执行一个控制器，该控制器在无限循环中执行功能。除此之外，我正在使用 Rufus Scheduler 来安排一个在特定时间后运行的函数，比如说 1 分钟。一旦函数在 Rufus 中正确执行，我会收到以下错误

    /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

这是一个本地库抛出的异常，而不是 Ruby 本身。看起来根本原因可能在于您正在使用的 tiny_tds gem：

/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新版本的 tiny_tds 以查看问题是否仍然存在？

edit：我看到它是最新版本；或许可以向 tiny_tds 维护者提出这个问题 - 请参阅 https://github.com/rails-sqlserver/tiny_tds
