i would start with google, look up the “how to ask smart questions” and if you founded it and read it come back to the list. but from the level of details you gave i presume you are a newbie linux administrator and founded the 1024 limitation in linux. to get over it modify the limits.conf in /etc/security/ and I presume you are using ubuntu so modify the /etc/pam.d/login and include the pam\_limits.so with full path 🙂 ---

Yes, newbie to linux (a year into it, still learning every day). I searched on Google but am unclear on server settings that impact this vs. nginx settings and what the numbers should be, etc. ---

put a ulimit -n 65000 or something like that in /etc/sysconfig/nginx or depending on the distro into the nginx init script greets ---

Under FreeBSD: sysctl kern.maxfiles=65535 sysctl kern.maxfilesperproc=60000 and then either restart nginx or reconfigure it with worker\_rlimit\_nofile set in config. Under Linux it should be something like: echo 65535 \> /proc/sys/fs/file-max (never tested). Consult your OS docs for instructions how to make this changes permanent (usually you have to add them into /etc/sysctl.conf). Maxim D. ---

I found the solution for the same problem on my environment, ( Solaris 10 ) here: [http://www.cyberciti.biz/faq/linux-unix-nginx-too-many-open-files/](http://www.cyberciti.biz/faq/linux-unix-nginx-too-many-open-files/) Quoting: … "Then open the nginx configuration file (default: /etc/nginx/nginx.conf) and the following line right after the “worker\_processes” entry line ``` worker_rlimit_nofile 20480; ``` Once both changes are made, run the Nginx lint to make sure no errors have been introduced: ``` # nginx -t 2010/11/01 17:07:46 [info] 9520#0: the configuration file ``` /etc/nginx/nginx.conf syntax is ok 2010/11/01 17:07:46 [info] 9520#0: the configuration file /etc/nginx/nginx.conf was tested successfully and then restart Nginx" Thank to them I solved my problem 🙂 hope this helps… Posted at Nginx Forum: > **[Re: too many open files](https://forum.nginx.org/read.php?2,6300,215117#msg-215117)** > > how to handle? 2009/09/10 10:09:30 \[alert\] 9691#0: accept() failed (24: Too many open files)
