Is node2 still up at this point? The only reason the depth_to_cloud node
should be retrying those connections is if it died at some point, or if its
connection got killed in some other way.
You mentioned you're running against latest -- there have been some bugs
fixed with the retry logic recently that only went out to cturtle. You may
want to try switching over.

Those roscpp_internal log messages don't get sent to rosout unless you've
enabled DEBUG output in general -- is the rest of your system sending a lot
of messages to rosout?
