Ruby:打开的文件太多@rb_sysopen [英] Ruby: Too many open files @ rb_sysopen

问题描述

使用 File.new(big_file)(不关闭)打开文件 1016 次 (Ubuntu) 或 1017 次 (CentOS) 后，似乎有一个限制，它引发了:

After opening a file with File.new(big_file) (without closing it) 1016 times (Ubuntu) or 1017 times (CentOS), it seems there is a limit and it raises:

Too many open files @ rb_sysopen - big_file (Errno::EMFILE)

有什么办法可以提高这个限制吗?

Is there any way to raise that limit?

在我的系统上，ulimit 设置为 unlimited.

On my systems, ulimit is set to unlimited.

推荐答案

• EMFILE 在您的进程中打开的文件过多.
• ENFILE 在整个系统中打开的文件太多.
• EMFILE is too many files opened in your process.
• ENFILE is too many files opened in the entire system.

所以 Errno::EMFILE 是由于 ruby​​ 进程打开了太多文件.这个限制大概设置为默认的1024 可以看到:

So Errno::EMFILE is due to the ruby process opening too many files. This limit is probably set to the default 1024 can be seen with:

$ulimit -n
1024

代替:

$ulimit
unlimited

您可以使用此方法提高限制.
