Hi, sorry for the technical spam in this forum, but we've been suffering this show-stopper for 3 years, and I cannot imagine how it's not also blocking other people. Maybe we're doing something wrong? - We have a robot with around 200 services - From long ago, we avoid completely non persistent ROS services. This is because, when they're often used (at a few Hz), they create thousands of TCP sockets, which heavily affects the machine performance. - But a big problem with persistent services is that clients hang when the service is rebooted. See https://code.ros.org/trac/ros/ticket/2742 - Also, we have just found out that both in fuerte and groovy, clients freeze when a ROS service returns a false. At least with Ubuntu 12.4 See https://github.com/ros/ros_comm/issues/168 Anybody had these problems? Any workaround?
