====== Debug ====== commande pour voir ce qui se passe dans un process First find the rserver process-id. ps auxw | grep studio rstudio-server 7035 0.0 0.0 362488 4480 ? Ssl 16:37 0:01 /usr/local/lib/rstudio-server/bin/rserver Note the second number that appears on the output of a row containing the string rstudio-server/bin/rserver. In the case above the process-id is 7035. Then trace rserver sending the output to a file. The number after -p should be the rserver process-id. The funky -e option is used to cut-down noise from Java's thread management. sudo strace -f -e 'trace=!clock_gettime,gettimeofday,futex,timerfd_settime,epoll_wait,epoll_ctl' -p 7035 -o trace.txt Login and wait for the error message to appear. Stop the tracing by pressing ctrl-c. Open the file with your favourite editor, and search for the string exit_group. The lines above it are likely to indicate the error in rsession. In my case it was a symbolic link from .rstudio to a missing directory. 7529 mkdir("/home/dds/.rstudio", 0777) = -1 EEXIST (File exists) 7529 stat("/home/dds/.rstudio", 0x7ffff37419b0) = -1 ENOENT (No such file or directory) 7529 write(2, "07 Feb 2015 16:46:53 [rsession-d"..., 395) = 395 7529 sendto(3, "<11>Feb 7 16:46:53 rsession-dds"..., 398, MSG_NOSIGNAL, NULL, 0) = 398 7529 exit_group(1)
