I have a lot of below error in error.log.  
Open /home/user/… failed (24 too many open files.  
So i search in google and config below files.  
Limits.conf , sysctl.conf nginx.conf for adjust rlimit nofile.  
I set open file limit to 999999 and fs.max to 2000000.

When i am geting error i used command ( lsof | wc -l ) for see total  
open  
file that it show 16000.  
I use command ( cd /proc/nginx pid/limits ) it show max open file  
999999.  
Now i am geting above error yet.  
So what is problem?
