Too many open files and unix

Hi,

tonight I force-restarted nginx and everything seems to be fixed.  
Checking the sockets shortly after restart returned 48 sockets for the 
master process and 36 sockets for worker processes.

Now, 14 hours later sockets raise again - there are now 1128 sockets for 
the master and 1116 for workers.

I noted the difference of 12 sockets between master and workers. Theese 
seem to be those for communication between master and workers, but I 
don't know how to classify this information.

Is this the intended behaviour of nginx or is it a bug in Ubuntus 
ppa-package of nginx?

Regards, Axel
