Known Issues

Dev-environment

Using Docker container in VScode can sometime lead to memory leak. This usually happens after switching the active git branch.
Symptoms include repeated port forwarding, as evident in the Ports tab in VScode, which can be self-triggered or triggered when launching a ROS process. Memory usage will increase exponentially in the process, eventually leading to the computer freezing completely.

Currently, there's no known permanent fixes. The following recovery procedure is a band-aid solution that helps you resume your development progress.

Disconnect the remote connection to the container image on VScode, and close VScode.
Clean uninstall VScode:

sudo apt-get purge code
rm -r ~/.vscode/
rm -r ~/.config/Code/

Instead, if VSCode has been installed with snap, the first line becomes:

sudo snap remove code

sudo snap install code --classic

Reinstall VScode Dev-container extension
If the issue still persists, try the following
After clean reinstallation of VScode, DO NOT sync to your VScode extensions and enable only Dev-container
After VScode has been wiped clean, flush the built container images and volumes:

sudo docker system prune -a
sudo docker volume prune -a

Then reinstall VScode, and rebuild image as normal.
