error message: "error sending response: Host unreachable" even if the service call behaved as exepected

[paoloelle]

Environment

• OS Version: Ubuntu 22.04
• Source or binary build? Binary Gazebo Fortress

Description

• Expected behavior: Some message that tells me if the service call behaved as expected even if an error occurred in sending the response to the service
• Actual behavior:
  I'm just implementing a simple scenario where I have a robot and a couple of simple objects that need to be moved in the arena with a certain frequency. I have a bash script that allows me to do that. The problem that I'm facing is that, even if the robot and the objects are moved as expected, I keep seeing the message [ruby $(which ign) gazebo-1] NodeShared::RecvSrvRequest() error sending response: Host unreachable when the timeout for the service is triggered (Service call timed out).

I guess the issue can be related to #243.

Steps to reproduce

1. Run a simple simulation with some objects
2. Change the position of the objects continuously

Output

This is the output that I get when the timeout for the service call expires (even if the object is moved to the new position as expected):

• [ruby $(which ign) gazebo-1] NodeShared::RecvSrvRequest() error sending response: Host unreachable
• Service call timed out
