Hello,

I have a video data being streamed into a local host (to a socket). When I run my executable using rosrun it works well, but when I use roslaunch to run the same node, it says the resource is temporarily unavailable (error from the socket).

The error message I get is this: process[cmvideo_node-1]: started with pid [9553] VDS: unknown host: __name:=cmvideo_node Can't initialise vds client (returns -2, Resource temporarily unavailable) terminate called after throwing an instance of 'class_loader::LibraryUnloadException' what(): Attempt to unload library that class_loader is unaware of. [cmvideo_node-1] process has died [pid 9553, exit code -6, cmd /home/providentia/Documents/bridge_demo/workspace/cm_sim/devel/lib/cmvideo/cmvideo_node __name:=cmvideo_node __log:=/home/providentia/.ros/log/395ae26a-80d3-11e7-abe7-f48e38a43ac3/cmvideo_node-1.log]. log file: /home/providentia/.ros/log/395ae26a-80d3-11e7-abe7-f48e38a43ac3/cmvideo_node-1*.log all processes on machine have died, roslaunch will exit shutting down processing monitor... ... shutting down processing monitor complete done

I use the following for rosrun: 'rosrun cmvideo cmvideo_node'

And I use the following launch file: <node pkg = "cmvideo" type="cmvideo_node" name="cmvideo_node" ></node>

I know it's not a syntax problem, because the error message I get from the roslaunch is not from ros but from my executable file. Thank you for your help in advance!
