The IPC channel still there, doing an unlink of smq-server-rtu-slave comes the the applications are not shut down gracefully, e.g. with kill -9. In this case they cannot clean up their resources so it happens on restart.

The RouDi log also just states that the application was killed and not shut down properly.

It might also happen when no signal handler is used. You can have a look at the examples on how to do it properly.

thanks,I found the problem。 If I call right away : iox::runtime::PoshRuntime::initRuntime(runtime_name), Resources are not allocated。I invoke the request-response mode and create the service. the service will be panic.

I'm not sure what you mean. Can you describe your problem in more detail?
