[Bug] zenoh_bridge_ros2dds fails during runtime with 100% CPU

[Timple]

Describe the bug

zenoh_bridge_ros2dds fails during runtime. It blows to 100% CPU and doesn't allow connections to port 7447 anymore.

To reproduce

1. Start with a really busy network:

$ ros2 topic list | wc -l
229
$ ros2 node list | wc -l
WARNING: Be aware that there are nodes in the graph that share an exact name, which can have unintended side effects.
111

2. Run the bridge in a seperate docker:

  zenoh-bridge:
    image: eclipse/zenoh-bridge-ros2dds
    command: --listen tcp/0.0.0.0:7447
    environment:
      - ROS_DISTRO=iron
    network_mode: host

3. Connect with the bridge on the other side:

4. Validate port with telnet:

System info

Ubuntu: 22.04
ROS: Iron
Docker image: latest (today)
Local bridge: main (today) from source, but also latest docker fails the same

Other

Restarting the docker on the robot does resolve the CPU usage (back to few %). But still no connection possible.

I have the same issue

[jeaninevbrr]

Same here!

Are you still experiencing this issue with image eclipse/zenoh-bridge-ros2dds:1.0.0-rc.2 ?
