Hello,

I am using ROS2 galactic on ubuntu 20.04 server running on an rpi4. I was interacting with the rpi over ssh with it directly connected to my macbook.

In testing a service/client node pair that I had written I encountered an error that crashed the client node. The client node had run successfully multiple times until that crash. The following was output to all other running ROS2 programs:

tev: ddsi_udp_conn_write failed to udp/192.168.2.2:54606 failed with retcode -1 
tev: ddsi_udp_conn_write failed to udp/192.168.2.2:54472 failed with retcode -1 
tev: ddsi_udp_conn_write failed to udp/239.255.0.1:7400 failed with retcode -1

I am new to ROS2 and would appreciate any pointers on where to start in debugging this issue.

Thanks!

Hello.

I think the error is around dds, so why don't you change rmw to FastDDS? This document is helpful.
