You *can't* restart Nginx, or restarting it doesn't help?

Unless you have 5 or more cores, then that's almost certainly too many.
Try one worker process per core (maybe even just one, unless you are
serving tons of static files) and 1024 worker_connections.

I have no idea if this is related to the 50x errors you get.

I'd start with the error log and some details about your setup (starting
with your OS, Nginx version, and maybe what you are serving).
