socket.accept错误24：许多打开的文件 [英] socket.accept error 24: To many open files

问题描述

我在Ubuntu 9.10中打开文件时遇到问题，在Python2.6中运行服务器
主要问题是，我不知道为什么这样..

我已设置

ulimit -n = 999999

net.core.somaxconn = 999999

fs.file-max = 999999

和lsof给我约12000个打开文件，当服务器运行。

还有我正在使用epoll。

但是经过一段时间，它开始放弃： / p>

文件/usr/lib/python2.6/socket.py，第195行，接受
错误：[Errno 24]打开文件太多

如果没有达到文件限制，我不知道如何达到文件限制。

感谢帮助）

解决方案

配置最大打开连接的参数。

/etc/sysctl.conf

add：

  net.core .somaxconn = 131072 
 fs.file-max = 131072 
  

然后：

  sudo sysctl -p 
  

在/usr/include/linux/limits.h

更改： / p>

  NR_OPEN = 65536 
  

在/etc/security/limits.conf

add：

 code> * soft nofile 65535 
 * hard nofile 65535 
  

I have a problem with open files under my Ubuntu 9.10 when running server in Python2.6 And main problem is that, that i don't know why it so..

I have set

ulimit -n = 999999

net.core.somaxconn = 999999

fs.file-max = 999999

and lsof gives me about 12000 open files when server is running.

And also i'm using epoll.

But after some time it's start giving exeption:

File "/usr/lib/python2.6/socket.py", line 195, in accept error: [Errno 24] Too many open files

And i don't know how it can reach file limit when it isn't reached.

Thanks for help)

解决方案

Params that configure max open connections.

at /etc/sysctl.conf

add:

net.core.somaxconn=131072
fs.file-max=131072

and then:

sudo sysctl -p

at /usr/include/linux/limits.h

change:

NR_OPEN = 65536

at /etc/security/limits.conf

add:

*                soft    nofile          65535
*                hard    nofile          65535
