Thanks Michael for replying and giving me the issue details. I am trying to understand in what scenarios we may hit this issue. I checked the issue. It states that "This can happen when the configuration is changed and reloaded while we are executing a service.". Can you also please explain what does configuration changed and reloaded mean? Does it mean doing some changes in systemd unit file and then re-loading (via daemon-reload) it while the services are executing or the services are active and we are trying to disable or do a mask operation?
