I often have rosout processes that takes up a lot of cpu when nothing is running and I'm wondering where it would come from or if it's intended behavior.

Here is the output of htop when this happens. No node apart from the roscore is running at that point of time, but I've been running quite a few things prior. I'm using ros lunar on a source install on fedora27.

You might be running into ros/ros_comm/issues/1343.

There is no real fix for it at the moment, but it is being investigated.

Any way to revert to 1.12.12 ? Would cloning the repo in my catkin_ws and compriling it solve the issue or should I recompile my source install with this version ?

Placing the package in your workspace, checking out the 1.12.12 tag and recompiling would probably work. You'd have to recompile all other packages in your workspace as well though, or at least the ones that depend any of the packages inros_comm.

I was seeing the same symptom (albeit perhaps a different cause) running karmic on OSX. Killing the process only caused roscore to restart it, but I was able to band-aid the issue by sending the process a SIGSTOP:

killall -17 rosout
