Too many open files error
Too many open files error
assalam o alaikum,
I have a query and will be thankful for some good reply,
On asterisk server (centos 5.0) I am finding the frequent message in asterisk logs
Feb 17 11:38:38 NOTICE[3697] manager.c: Accept returned -1: Too many open files
when I check for open files
# lsof |wc -l
4022
I have increased the Open file limit for kernel much higher
# sysctl -a |grep file-max
fs.file-max = 655910
But still I am facing the" Too many open files" error
What may be the reason for that or what other parameter is needed to tune for avoidng the error.

How did u set the open files limit and what distro u r using?
I once tried to increase open files limit according to my requirements using PAM but was unseccessful. And I concluded in Vanilla distros PAM does not include this support and you have to compile the kernel. I was working for Squid and so the other solution was to compile the squid with increased open files support.
If u find a solution tell us too.
Otherwise u have to manage sessions properly in asterisk.

Distro is Centos 5.0 as mentioned earlier.
and to increase the system wide limit
vi /etc/sysctl.conf
fs.file-max = 655910
and #sysctl -p will reread this file.

Re:
Dear
Salam,
Post output of following command.
# ls -l /proc/`cat /var/run/asterisk.pid`/fd/ | wc -l
Further more take a look into /etc/security/limits.conf
You can use ulimit command and restart your asterisk.
# ulimit -n 4096
Best Regards.

aoa,
Problem still persist.
I have increased the limit and even rebooted the machine.

One thing which I am suspecting is that I have set the file open limit size to 4096.
and previous command #lsof -u root |wc -l
4000
indicating that 4000 files are opened by root user.
What maximum limit can I set for ulimit -n ?, mean what parameter memory , files system inodes etc need to be consider before setting its value too HIGH.

Thanks osama
It solved a big problem.
Above is very good link to the related problem.
The solution was to add the command "ulimit -n 65536" to the init script, prior to starting Asterisk.
