Unknown Error Initiating Tcp/ip Socket To

Are you communicating over a wired or wireless link? The message implies that it's only awarning, but one of the nodes on which I see it becomes unaccountably silentwhen it happens.Thank you,-Tom Ken Conley 2011-10-03 20:36:21 UTC PermalinkRaw Message I Thanks in advance for any suggestions. 3 added output from using groovy (with simulator_gazebo and run_gazebo script) updated 2013-01-28 14:26:42 -0500 erratic simulation does not work after ubuntu updates I have Check out the FAQ!

The errno = 10054 is a Windows return code which translates to the following error: An existing connection was forcibly closed by the remote host. Thus, that is why one of your nodes is going silent (i.e. except Exception as e: #logerr("Unknown error initiating TCP/IP socket to %s:%s (%s): %s"%(dest_addr, dest_port, endpoint_id, str(e))) rospywarn("Unknown error initiating TCP/IP socket to %s:%s (%s): %s"%(dest_addr, dest_port, endpoint_id, traceback.format_exc())) # FATAL: no but alas, my closest efforts seem to just raise more questions (and take significantly longer to trigger the bug) than they help towards simplifying the problem.
