[Noetic] image_raw topics randomly stop publishing, but nodelets and nodelet manager are not dying

[dhiren-rugged]

Bug
I have two Blackfly cameras and I am able to launch a camera nodelet manager that starts two separate Spinnaker camera nodelets that stream at 40FPS. 20-50 minutes in of run-time the image_raw topics randomly stop publishing. The nodelet manager and the nodelets show no sign of crashing in the command line, and no debug logs are outputted. Even running the nodelet manager with GDB does not spit out an error when this happens.

I'd also like to note that the cameras stay connected becaue I am able to consistently ping both after the topics cease to publish.

Has anyone had this same issue?

System details

• operating system/version: Ubuntu 20.04
• ROS version: Noetic
• camera model: Blackfly BFS-PGE-31S4M

Sorry, I only support my code, which is the ROS2 driver.
