This might be perfectly correct as long as the original connection 
was closed.

There is no such function in nginx, so it looks like you are using 
some 3rd party modifications.

You may want to start with compiling vanilla nginx as available 
from nginx.org without any 3rd party modules and/or patches and 
testing if you are able to reproduce the problem.
