Problem
On Workbench, code run by developers has the potential to spawn additional processes. Upon termination of the primary process, these sessions can remain in the background as zombie sessions.
Solution
These processes can be removed manually, however, Workbench has directives that can clean these up automatically for you. This involves adding the following directive to your Workbench server's /etc/rstudio/rsession.conf configuration file:
session-quit-child-processes-on-exit=1
From there, restart the Workbench and Launcher services:
sudo rstudio-server restartsudo rstudio-launcher restart
Note that this change will apply to newly created sessions. So you may need to manually delete any Zombie sessions that already exist.
