Accept returned -1: Too many open files????

[hammobru]

Hi, I was watching the "CLI" and saw the following message run across. What exactly does this mean?

Thanks in advance. I am running the following :


Intel Quad Core Xeon 2.83 MHZ 2 Gg Ram

VERSION: 2.0.4-121 BUILD: 80424-0442

Running All VOIP. Server load average is at 1.53 1.63 1.49 When this happened.

Thanks in advance.

[mflorell]

What is the CPU on that server?

How many concurrent calls were you running when this happened?

Asterisk version?

[linuxlover]

I was facing the same problem and have solved it by

Code: Select all

 

How are you starting Asterisk? We had the same problem when we were starting Asterisk from an init script. The problem was that we were increasing the open file limit in "/etc/security/limits.conf". From a system prompt ulimit was showing the increased open file limit, but here's the catch:

"limits.conf" is only applied to logins, so when Asterisk was run from an init script it was still bound to the default limit for open files: 1024. The solution was to add the command "ulimit -n 65536" to the init script, prior to starting Asterisk.

This was a tricky problem to debug, because once Asterisk bombed we would log in, stop the process, and restart it from the prompt. The new instance inherited the settings from "limits.conf" and everything ran fine until the next reboot.

I hope this helps, but if it doesn't here is some more useful information. "/proc/<pid_of_asterisk>/fd/" contains a list of Asterisk's open files. "ls -l /proc/<pid_of_asterisk>/fd | wc -l" will give you a rough count of the number of files Asterisk has open at any given moment. "lsof" will also list the open files on the system. Check out its man page for details


solution was to increase the open file limit before starting the asterisk.

[mflorell]

It should be noted that this solution does not work on all Linux distros. Sometimes you have to recompile bash with higher default open file values.

[linuxlover]

Thanks mflorell for addition.

I am using this on Centos 5.

[enjay]

What is the output of ulimit -n?

[TritenTech]

Hi, Ulimit -n shows 1024. Thats probably my problem. I need to change that.

Now I just have to figure out how.

Thanks again.

[mflorell]

keep in mind that ulimit values are per shell session, not per boot or user.

[linuxlover]

Hi,

To make it permanent add this in file /etc/security/limits.conf

Code: Select all

* soft nofile 16384
* hard nofile 16384


to increase the value immediately give at command prompt

Code: Select all

#ulimit -n 16384



To set this this limit on start up before starting asterisk and this line in /etc/rc.local file (above the line of asterik startup script)

Code: Select all

#ulimit -n 16384



Let me know if you still face any problem regarding that.

[enjay]

Definitely instantiate the ulimit command in the rc file...
