RTPS Error message: error: couldn't generate segment_name -> Function init
I have built ROS2 Foxy_Fitzroy for QNX system and now test ros2 nodes on it. Everytime I run any ros2_node on it, it generates the following error message
1970-01-01 00:07:25.381 [RTPS_MSG_OUT Error] error: couldn't generate segment_name -> Function init
Nevertheless the ros node runs fine functionally.
Could somebody explain what this error means, and tell me how to handle it?
