Disabled cloning of sockets without master process (ticket #2403). Cloning of listening sockets for each worker process does not make sense when working without master process, and causes some of the connections not to be accepted if worker_processes is set to more than one and there are listening sockets configured with the reuseport flag. Fix is to disable cloning when master process is disabled.
