Beware: if you started the nodes with roslaunch and there was no roscore already running, then restarting causes the old master to shut down and a new one to start up.

If that happens, you'll need to restart rxgraph (and everything else).

If that is your problem, starting roscore first in a separate window is a good work-around.
