Config looks sane and shouldn't cause any problems.

Most likely reason is shortage of some system resources, e.g.  
you've run out of memory or socket buffers.  Other possible 
reasons include:

- something like statefull firewall inbetween which run 
  out of states and dropping random connections;

- nginx workers dying for some reason, likely unrelated to this 
  particular server block.

Looking into error_log may be helpfull.  Note well: you may want 
to look into global error_log as well, not only the one defined 
for this particular server.
