(rospy) Broken pipe in service server #2227

Open MatthijsBurgh opened 2 years ago

MatthijsBurgh commented 2 years ago

I have a service server in python. My client runs in CPP.

When I stop my client, while a service call was active. I get the following error on my python server side.

Error processing request: 32Broken pipe
