Bug report

Required Info:

• Operating System:
  • Ubuntu 18.04
• Installation type:
  • Source
• Version or commit hash:
  • 8071da1
• DDS implementation:
  • Opensplice 6.9

Steps to reproduce issue

Terminal 1:

ros2 run intra_process_demo camera_node

Terminal 2:

ros2 run intra_process_demo watermark_node

Expected behavior

Both nodes run, passing data between them.

Actual behavior

Both nodes run, and data gets passed, but camera_node prints once:

[WARN] [rclcpp]: Intra process message no longer being stored when trying to handle it

And watermark_node continually prints:

[WARN] [rclcpp]: Intra process message no longer being stored when trying to handle it
[WARN] [rclcpp]: Intra process message no longer being stored when trying to handle it
[WARN] [rclcpp]: Intra process message no longer being stored when trying to handle it

I don't see this with image_pipeline_all_in_one or with image_pipeline_with_two_image_view

Not at the moment, no. I have a couple of other things that need to get done first, then I may have time to come back to this. In the meantime, if someone else wants to pick it up, that would be fine.
