Hello everyone,
a while ago, I contributed this PR #508. However, a small oversight is that I did not check for
rospy.is_shutdown()in the introduced while-loop. So if you manage to kill the node while it is still waiting for services, you receive a nasty message spam.This commit simply adds the missing check for a running node.
Best regards,
Martin
