This is likely a different issue, as open sockets are expected to
be seen as open file descriptors.
If you are using SPDY, please try without it, see these tickets
for similar reports:
https://trac.nginx.org/nginx/ticket/626
https://trac.nginx.org/nginx/ticket/714
If not, you may want to consider obtaining more information. The
http://wiki.nginx.org/Debugging contains some hints about
debugging socket leaks as well.

I wouldn't suppose it's safe, either. In the past it caused
segmentation faults at least once.
