17289#0: open socket #14 left in 39 connection

Hello,

I have installed Nginx 0.6.35 and got the following error:

[alert] 17289#0: open socket #14 left in 39 connection

After this error, the server crashed. At the time the server was under a
high load with high disk I/O.

This is what ‘nginx -V’ returns:

nginx version: nginx/0.6.35
built by gcc 4.1.2 20080704 (Red Hat 4.1.2-44)
configure arguments: --with-cpu-opt=amd64
–without-http_autoindex_module
–without-http_fastcgi_module --without-http_proxy_module
–with-http_ssl_module --with-http_stub_status_module
–without-http_ssi_module --without-http_userid_module
–add-module=/root/nginx-geoip-0.1 --with-md5=/usr/lib64
–with-sha1=/usr/lib64 --prefix=/opt/nginx --sbin-path=/usr/sbin/nginx
–conf-path=/etc/nginx/nginx.conf --pid-path=/var/run/nginx.pid
–http-log-path=/var/log/nginx/access.log
–error-log-path=/var/log/nginx/error.log
–lock-path=/var/lock/nginx.lock
–user=www --group=www

What could be the problem?

Kind regards,

Jeroen

I faced same problem in the begining. However it got resolved after
setting
following parameters properly:

user, worker_processes, worker_connections, keepalive_timeout,
tcp_nopush,
tcp_nodelay

Please post your ngix.conf to get the better idea.

Hi Jeroen,

A. Can you try following changes in your ngix.conf ?

  1. Comment following lines:
    client_body_buffer_size 8k;
    client_header_buffer_size 1k;
    client_max_body_size 1k;
    large_client_header_buffers 1 1k;
    client_body_timeout 5;
    client_header_timeout 5;

  2. Change following settings:
    user www
    worker_connections 2048;

  3. Enable logging error & access both logs

B. Are you using php+fastcgi? If yes then please see that whether it is
running & configured with ngix properly or not?

Hope it will help you.

Regards
NeeleshG

Hi NeeleshG,

A.

  1. I have commented out the buffer and timeout lines.
  2. Changed the user and worker_connections
  3. Logging was already enabled.

B.
I’m just using it for static files.

It’s working properly. It was working properly before as well. However,
when
I was generating a file of 10 GB on the same disk where the ‘document
root’
is, that’s when Nginx crashed.
I’ll let you know if the new configuration works.

Cheers,

Jeroen
