thanks @cderv for your quick reply. we run open source rstudio in a docker container with R 3.3.1 version. we have close to fifty-sixty users using on daily basis. we get users request saying that their session is hung and cant load or do anything with rstudio. those cases we generally clear their /tmp/Rtmp* of the users and kill rsession of user.what we expect is it a known issue or we have workaround.thanks
