r - Shiny 的服务器崩溃

Question

背景: 我在 RHEL 5 机器上运行 shiny-server，它一直以不可重现的方式崩溃。似乎node.js与错误有关..

错误如下:

 Error: write EIO
    at errnoException (net.js:901:11)
    at Object.afterWrite (net.js:718:19)

任何帮助将不胜感激!最坏的情况是我会安排一个 cron 作业来监控服务并在失败时启动它..

Answer 1

看起来我在这个问题上悬赏有点仓促。

答案在彼得发布的链接中。

Shiny 服务器的 1.3.0.403 版本有一个错误，它不能很好地与 DT 等软件包配合使用。升级到至少版本 1.4.0.721 应该足以解决这个问题。
