[R閃亮服務器分段錯誤

Question

我一直在我的Linux機器上運行閃亮服務器上得到以下分段錯誤：

-bash: line 1: 29254 Segmentation fault  R --no-save --slave -f \/opt\/shiny-server\/R\/SockJSAdapter\.R 
" 

它開始三天前在以前工作正常的應用程序。該應用程序不會在我的Windows機器上發生錯誤。我已經更新了機器上的所有軟件包和RStudio。我試圖找到答案，但關於Segfaults的信息很少。

我試圖重現錯誤並將代碼剝離爲最小值。我發現渲染文本和表格（base和DataTables）是可以的，但渲染任何plot（base，ggplot，plotly）會產生分割錯誤。下面是從JavaScript控制檯給出錯誤和錯誤消息的代碼。

我也試圖通過從RStudio Linux機器上的Web瀏覽器啓動代碼，看看我是否能得到更多的信息，但它只是crached給我下面的錯誤信息： Rstudio browser error message

你有什麼想法可以在它後面或如何解決它？

預先感謝您。

PS：我用閃亮的儀表板，但我得到了同樣的信息，當我運行它作爲一個經常閃亮應用

Answer 1

我正經歷着完全相同的問題（有光澤的儀表盤+ rhandsontable + GGPLOT2）。

至於Bárbara Borges suggested in a comment，將options(java.parameters = "-Xss2560k")添加到ui.R解決了我的問題。
