wait_for_service waits indefinatly when working with discovery server [13708]

Open amfern opened this issue 3 years ago • 4 comments

Expected Behavior

wait_for_service block until the service is discovered

Current Behavior

When service and client are created in the same time, the wait_for_service will hang indefinably. This doesn't happen when using multicast. Even as one of the nodes hangs on wait_for_service, I can run the same client and get a response

Steps to Reproduce

  1. start the service and client in the same time

The service and client must be started at the same time for the issue to appear, we use the systemd to run ros2 nodes on nvidia jetson inside a ros:galactic container, so this bug occures pretty frequently on our system.

I attached a script reproduce-wait-for-service-hang.sh that pretty easily reproduces the bug, a YouTube video and a docker image

This docker image will reproduce the bug docker run -ti --rm amfernus/reproduce-wait-for-service-hang:latest

Hi @amfern , thanks for your contribution and sorry for the late reponse. Could you check if this issue is happening in current Fast DDS v2.11.0, or in 2.6.x with ROS2 Humble?

hi @JesusPoderoso, Thank you for taking look at this issue.

I was able to reproduce it with ros2 humble.

Dockerfile:

Hi @amfern, thanks for the reproducer. I was able to reproduce the issue, and i also tested the scenario with simple discovery, using unicast, multicast and initial peers, and it worked as expected. That means for me that the issue is discovery server related. This issue is now categorized as bug, and we will look for solving this.

I reproduced this issue too with discovery server ros2 service list returns nothing
