my rstudio server was hanging too often while loading starting r shiny app. So after googling around i tried to stop and start the rstudio server again. i also tried to kill all process running on 8787 port. But had no luck solving the issue. now r studio server keeps waiting while opening on web browser.
I have used below command to kill process running on 8787 port. after running the command there was no result.
sudo kill -TERM 20647 (20647 is port where rserver process is listening. i got this port number after running 'sudo netstat -ntlp | grep :8787' command).
to stop and restart r studio server, i used below command sudo rstudio-server stop sudo rstudio-server start
expected result is working sr studio server which doesnt hang while loading shiny app. after running status command i found below error logged for rstudio server.
