Introspection for camp node gives error.

[bsb808]

I am trying to understand the various interfaces involved in the example...

roslaunch project11_simulation sim_local.launch

When I run the example, I can successfully use the rosnode command to examine most nodes, e.g.,

@a873a0f23cc1:~$ rosnode info /operator/remote_manager 
--------------------------------------------------------------------------------
Node [/operator/remote_manager]
Publications: 
 * /ben/piloting_mode/manual/helm [marine_msgs/Helm]

 * /rosout [rosgraph_msgs/Log]

But, when I try to do the same for the camp node, I get an error...

I restarted everything a few times and the issue went away. When/if I can reliably reproduce the issue, will re-open.
