我尝试了 2 个不同的网站，但无法理解两者之间的区别.

I tried 2 different sites but can't understand difference between the two.

[EMFILE]
Too many open files.
[ENFILE]
Too many files open in system.

# define ENFILE      23  /* File table overflow */
# define EMFILE      24  /* Too many open files */

此外，我收到 errno 24 并且套接字调用在第 974 次失败.(AF_INET UDP 数据报套接字)

Also, I am getting errno 24 and socket call failing at 974th time. (AF_INET UDP datagram socket)

当我执行 cat/proc/sys/fs/file-max 时，我看到的值为 334076ulimit -n 显示 1024

When I did a cat /proc/sys/fs/file-max I am seeing a value of 334076 ulimit -n showing 1024

知道可以做些什么来增加限制吗?

Any idea what can be done to increase limit?

推荐答案

对于 1) 两个错误码都是关于打开文件过多的情况.EMFILE 在您的进程中打开的文件太多.ENFILE是整个系统打开的文件太多.

For 1) Both error codes are about the situation with too many opened files. EMFILE is too many files opened in your process. ENFILE is too many files opened in the entire system.
