Subject: [ros-users] problems with persistent services
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?

Thank you
