ros2cli: NodeStrategy init Hanging

https://github.com/ros2/ros2cli/blob/094bcd9d8ba0a381f3598eeaba03eb45ed3d2df1/ros2cli/ros2cli/node/strategy.py#L25

Hangs within this method. Issue: #ros2/ros2/issues/1093

can recreate with command: ros2 topic list (hangs with constant increase of memory allocation until manually killed)

and directly recreate with:

/root/wsdev/src/jtbot/src/topicList.py 
lv = ListVerb()
v.main(args=None)

Environment:

ros-foxy-desktop/focal,now 0.9.2-1focal.20210226.004308 amd64 [installed]
Docker ubuntu 20.04 
python3.8/focal-updates,focal-security,now 3.8.5-1~20.04.2 amd64 [installed,automatic]

I’m still having the same issue on my system.

It seems the only temporary fix is restarting my system. ros2 daemon stop && ros2 daemon start also hangs…

I first noticed this issue while I was debugging C++ code. It seemed to be causing issues with Cyclone

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.

Hi,

Same issue here. The only solution I found so far is to reboot.

I have the same issues, indeed using Cyclone too.

Yeah. All I can say is that it is not very repeatable but it happens about once or twice a day for me in repeated use. Will keep trying to gather more information. If there is something you want me to look at when this happens, let me know.
