Hi ROS community.

I have the problem where my lifecycle nodes will hang on activation, but only if i use more then 2 nodes. The nodes does not hang every time, they seem to hang at random, though with the example docker below it is repeatable. Its likewise annoying as launch a new node, in its own container, seems to activate the previously stuck nodes and allows for them to finish their configuration.

In order to demonstrate the supposed bug, i have created a minimal reproducible example: example

I'm unsure how i would proceed with debugging this, as there is no prints to the console. For versions, the docker is build with Ubuntu 22.04 and the ROS2 version is humble. FastDDS is likewise the newest version.

I have however reproduced this with the binaries from the official repository, and the bug is especially present on low power systems such as a Jetson nano.

Is this a known bug? Or is there a know workaround?
