Hello Everyone, I get the following error when i let run some small example from ros2
[RTPS_TRANSPORT_SHM Error] Failed init_port fastrtps_port7428: open_and_lock_file failed -> Function open_port_internal
has anyone experienced this before? After error issue, the program is still running correct. i would like to fix it
I found a solution that worked for me. The problem are different rmw_fastrtps versions.
Probably Dolly is built with a different version as your normal ros2 foxy system.
To check your available version do:
ros2 doctor --report | grep fastrtps
The newest version for Ubuntu 20.04 and ROS2 Foxy should be:
rmw_fastrtps_shared_cpp = 1.3.1
rmw_fastrtps_cpp = 1.3.1
This bug fix removes the problem: commit
But you have to install it on every system.
To update these packages either do separate:
sudo apt update && sudo apt install ros-foxy-rmw-fastrtps-cpp ros-foxy-rmw-fastrtps-shared-cpp
or update all old packages with:
apt update && apt dist-upgrade
A restart is required after you already encountered the error once!

Yes, I am getting this now trying to start a python app. Nothing has changed with the code, seems to be an underlying system issue. Were you able to resolve it?
