Specific user session hanging on RStudio server
Hi,
I'm using the latest dev .95.52 release of RStudio server on a
64-bit Ubuntu 10.04 LTR machine.
I had my R session go wacky on me yesterday (locked up) and now when I try to log in (via chrome on a W7 machine) RStudio does not produce my session. I get the error message: 'The RStudio server is taking a long time to respond. It is possible that your R session has become unresponsive. Do you want to terminate the currently running R session?'
I cannot terminate the session from the web interface - at least nothing happens.
Logging into a new test user session works fine. Looking at the processes from system monitor I see that when I try to log in to RStudio Server a new rsession starts and gets really big >4 Gig. I can see the PID of the session under my username with the RStudio server facilities, but cannot access it. I think my session has gotten corrupted.
If I kill the rsession process when I try to log in again my session still locks up. I have rebooted the server, stopped and restarted RStudio Server, reinstalled..
How can I reset my user session to a fresh one, or diagnose what the problem is?
Best,
Brent

Okay,
I fixed this by renaming my /home/.rstudio folder then restarting rstudio server and logged in to get a new clean user session.

FYI,
Of course when my session got fried I had not saved some extensive edits to a specific script. Renaming the .rstudio folder gave me a new session, but naturally the edits were not there.
I found that by copying the old .rstudio/source_database folder to the new rstudio profile I could retrieve these edits...promptly saved...
Might be useful for someone else,
Brent

Hi Brent,
Glad you got through this, we have it on our list to create a "safe mode" where you can launch a clean session and then optionally recover the pieces of it which might have caused R to take a long time to load.
