Thank you for your advice @audrow I’m now using Humble with Ubuntu 22.04 and it’s working fine

I’m using osrf/ros:foxy-desktop as the base image for my docker. The issue is random and I can’t really detect a pattern to it yet. It happens when I run my application and then I want to list topics and nodes. Closing the application doesn’t seem to help. When it happens, only a reboot of the host seems to fix it. Anyway, I will keep trying to get more information on the failure mode.
