Hi, I am using both UR-RTDE and RTDE C++ API to connect 2 or 3 clients (different process for testing purpose) on port 30004, to listen to robot variables (like joints, speed, tcp offset, …). And sometimes, I got an “End of file” ASIO error which suggests that the robot has closed all the sockets. …

Hi, back on this. There were two issues here. The UR_RTDE lib used is quite slow, so I need to reduce the frequency with multiple receivers. The physical connection was faulty with some “invisible” kernel network disconnection.
