套接字。接受错误24:对许多打开的文件

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..

在运行Python2.6版本的服务器时，我在Ubuntu 9.10下有一个打开文件的问题，主要的问题是，我不知道为什么会这样。

I have set

我已经设置

ulimit -n = 999999

ulimit - n = 999999

net.core.somaxconn = 999999

net.core。somaxconn = 999999

fs.file-max = 999999

fs。file-max = 999999

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

lsof在服务器运行时向我提供12000个打开文件。

And also i'm using epoll.

我还用了epoll。

But after some time it's start giving exeption:

但过了一段时间后，它开始给人感觉:

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

文件“/ usr / lib / python2.6 /插座。第195行，accept error: [Errno 24]打开的文件太多

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

我也不知道当它没有达到文件限制时，它是如何达到文件限制的。

Thanks for help)
