Hello,

today I had too many open files and I need some advice to investigate in  
this issue.

I googled around and found a lot information how to solve this issue  
(e.g. [Handling nginx's too many open files even I have the correct ulimit](http://forum.nginx.org/read.php?2,234191,234191))  
I finally was able to get rid of the error.

But I wondered about nginx behaviour with unix sockets and open files on  
my machine, because every worker process on my machine opened 15892  
sockets which seems to be very much compared to other machines I took a  
look at. On other machines I only have as much open sockets as worker  
processes.

Perhaps someone can point me to the right direction to debug and solve  
this.

The system has 16 cores and 16 GB Ram (10 GB RAM used, Load average:  
0.3) Ulimits are set to

> su - www-data -s /bin/bash  
> $ ulimit -Hn  
> 32768  
> $ ulimit -Sn  
> 16384

In nginx.conf I set

> user www-data;  
> worker\_processes 12;  
> worker\_rlimit\_nofile 65536; # raised from 16384  
> worker\_connections 65536; # raised from 16384

Checking the open files of the master process returns

> root@nginx:~ # lsof -p 31022 | wc -l  
> 16066

> root@nginx:~ # lsof -p 31022 | grep socket | wc -l  
> 15904

Checking the open sockets returns for every single worker process 15892  
I restarted nginx several times, but this does not change anything.

This is what I get when I raise errorlog level to debug:

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

Hello,  
Can you tell the output from this command ps -eLF |grep www-data |wc -l  
?  
And What does /proc/sys/fs/nr\_open output ?

Subject: Too many open files and unix

Hello,

today I had too many open files and I need some advice to investigate in  
this issue.

I googled around and found a lot information how to solve this issue  
(e.g. [Handling nginx's too many open files even I have the correct ulimit](http://forum.nginx.org/read.php?2,234191,234191))  
I finally was able to get rid of the error.

But I wondered about nginx behaviour with unix sockets and open files on  
my machine, because every worker process on my machine opened 15892  
sockets which seems to be very much compared to other machines I took a  
look at. On other machines I only have as much open sockets as worker  
processes.

Perhaps someone can point me to the right direction to debug and solve  
this.

The system has 16 cores and 16 GB Ram (10 GB RAM used, Load average:  
0.3) Ulimits are set to

> su - www-data -s /bin/bash  
> $ ulimit -Hn  
> 32768  
> $ ulimit -Sn  
> 16384

In nginx.conf I set

> user www-data;  
> worker\_processes 12;  
> worker\_rlimit\_nofile 65536; # raised from 16384  
> worker\_connections 65536; # raised from 16384

Checking the open files of the master process returns

> root@nginx:~ # lsof -p 31022 | wc -l  
> 16066

> root@nginx:~ # lsof -p 31022 | grep socket | wc -l  
> 15904

Checking the open sockets returns for every single worker process 15892  
I restarted nginx several times, but this does not change anything.

This is what I get when I raise errorlog level to debug:
