我在Linux机器上运行的Shiny Server上遇到以下分段错误：
-bash: line 1: 29254 Segmentation fault R --no-save --slave -f \/opt\/shiny-server\/R\/SockJSAdapter\.R
"
它是在三天前开始的一个应用程序，以前工作正常。该应用程序不会在我的Windows计算机上出错。我已经更新了机器上的所有软件包和RStudio。我试图找到答案，但关于Segfaults的信息很少。
我试图重现错误并将代码剥离到最低限度。我发现渲染文本和表格（base和DataTables）没问题，但渲染任何绘图（base，ggplot，plotly）会产生分割错误。下面是从JavaScript控制台提供错误和错误消息的代码。
我也尝试通过Linux机器上的RStudio的Web浏览器启动代码，看看我是否可以获得更多信息，但它只是给我提供以下错误消息：Rstudio browser error message

你知道它背后可能是什么或如何解决它？
先感谢您。
PS：我正在使用Shiny Dashboard，但是当我将它作为常规的Shiny应用程序运行时，我得到相同的消息
我遇到了完全相同的问题（闪亮的仪表板+ rhandsontable + ggplot2）。
Bárbara Borges suggested in a comment，在options(java.parameters = "-Xss2560k")and添加ui.R解决了我的问题。
