如何解决RStudio Server: R is taking

Rstudio server 在运行的时候自己断掉了，重新登录提示：
RStudio Server: R is taking longer to start than usual

搜索之后仍然没有解决
RStudio Server: R is taking longer to start than usual
rstudio - Hosted R Studio hangs when trying to open - Stack Overflow

最后再nicker老师的帮助下成功解决：

总结：删除session-*文件 + kill r

1、 rm -rf ~/.rstudio/sessions/active/session-* 
2、ps -u userid 查看自己账户下的运行程序，再去kill 掉rsession

问题就解决了
