Nginx uses a configurable, fixed number of worker processes, handling many connections per worker process. This allows Nginx to maximize throughput on any variety of multi-processor and/or multi-core configurations.

If one worker dies, any of the connections it's handling will close, but connections associated with the other worker processes stay alive. I'm not 100% sure, but I believe the master process will restart a worker if it dies.

All that said, I've never seen Nginx crash (except when playing around with an experimental third-party module - but never in production). For any production server, you should be using some form of monitoring daemon that will alert in case of a failure and automatically restart the web server process.
