打开的文件太多

Question

当我打开 Lutris 然后打开 LOL 客户端时，就会发生这种情况。游戏永远不会好。我尝试了很多东西，但永远无法更改打开文件限制。如何解决这个问题？

当“Too Many Open Files”错误消息写入日志时，它表明进程的所有可用文件句柄都已被使用（这也包括套接字）。

在大多数情况下，这是应用程序的某些部分泄漏文件句柄的结果。ulimit 是 unix/linux 中的命令，它允许为所有属性设置系统限制。

ulimit是 unix/linux 中的命令，它允许在您需要增加最大值的情况下为所有属性设置系统限制。不。打开的文件数

ulimit -n   <large value in your case 1000000>

or 

sysctl -w fs.file-max=1000000

and

/etc/security/limits.conf or /etc/sysctl.conf:
change 

fs.file-max = 1000000

要确定打开文件的数量是否在一段时间内增长，请发出 lsof 以定期根据 PID 报告打开的文件。例如：

lsof -p [PID] -r [interval in seconds, 1800 for 30 minutes] > lsof.out

如果您无权访问 lsof 命令，这将特别有用：

ls -al /proc/PID/fd

设置 ulimit 的指南
