Rprofile which takes too long to run or throws errors during startup. Two of the most common session startup problems are (1) oversized global R environments, which take a long time to load into memory when the session is resumed, and (2) problematic code in. ![]() We recommend that you send these files to Posit support to aid in troubleshooting any session launch issues should they arise. Rsession-diagnostics-enabled = 1 rsession-diagnostics-strace-enabled = 1 These files will grow very large in a short amount of time so remember to turn off this option and do not use it to capture extended session runs. Before using this setting, ensure that strace is installed and is available on your users’ path. Strace information can be included in the diagnostics file by adding the rsession-diagnostics-strace-enabled flag as shown below. Otherwise sessions may fail to launch due to the default location under /tmp not being available in the containers. To diagnose containerized sessions (e.g. Kubernetes) launched via the Job Launcher, set rsession-diagnostics-dir to a shared folder mounted in the container via /etc/rstudio/launcher-mounts. Remember to turn the option off when you are done to prevent diagnostic information from accumulating in this directory. If it does not exist, Posit Workbench will attempt to create it and set its permissions to Read/Write/Execute for everyone (file permissions of 777). Rsession-diagnostics-dir = /tmp/diagnosticsīe aware that this directory should be accessible by all users of the system. You can specify a supervisor (and the arguments which control it’s behavior) using the rsession-exec-command setting. You may also wish to run RStudio Pro Sessions under a program supervisor that modifies their environment or available resources. To learn more about setting environment variables with PAM you should consult the PAM Sessions section as well as the documentation on the pam_env module here. On Debian/Ubuntu systems, the default PAM profile run by Posit Workbench includes the environment variables defined in /etc/security/pam_env.conf and /etc/environment. It’s also possible to append paths to the LD_LIBRARY_PATH environment variable using the rsession-ld-library-path option (see previous section for details).Īnother source of environment variables are PAM sessions. RStudio Pro Sessions inherit environment variables that are explicitly exported from the profile scripts described above. Rsession-no-profile = 1 Environment variables
