2019-03-04 02:28:29 -0500 | marked best answer | ROS2/pendulum demo (and rttest/example_loop) get killed if 8GB free RAM is not satisfied. Hi ! I am using Ubuntu 16.04 with a real-time patched kernel (4.14.93-rt53). I have tested my system with cyclic tests and am happy about the realtime performance. I have built and installed Ros2 (Crystal Clemmys) according to this manual: https://index.ros.org/doc/ros2/Instal... . The talker and listener examples work fine. When I try to run the pendulum demo ( https://index.ros.org/doc/ros2/Tutori... ) I get an unexpected output: I could get rid of the line: I have tried to give the rights according to this: https://index.ros.org/doc/ros2/Tutori... I can also see (after logon/logoff) that the rights are updated accordingly: Now the output is without this line, but still gets killed: I have found a very similar (unanswered) question and initially posted mine (by mistake) as an answer here: https://answers.ros.org/question/3030... I would be happy to receive any Input. Since I am inexperienced with Ros, it might very well be some rookie mistake. Thank you! Nicolas Update: Testing with rttest and debugging with gdb According gvdhoorn's suggestion I have tested To debug the and received the following output: (more) |
