ubuntu - 如何增加在 Ubuntu 上运行的 Asterisk 的打开文件描述符

Question

我遇到了这个，我发现只有一篇关于这个的帖子有修复，但不是那么清楚，而且已经有几年了。
Ubuntu 20.04
Asterisk 16.9
错误信息:

[Jul 20 21:37:16] WARNING[1742] alertpipe.c: Failed to create alert pipe with eventfd(), falling back to pipe(): Too many open files
[Jul 20 21:37:16] WARNING[1742] alertpipe.c: Failed to create alert pipe: Too many open files

Asterisk PID:1130
检查进程的限制。最大打开文件软限制为 1024

编辑/etc/asterisk/asterisk.conf

[options]
maxfiles = 4096                 ; Maximum amount of openfiles.

停止 Asterisk 进程

# systemctl stop asterisk

确保 Asterisk 已停止

# ps -ef | grep asterisk

启动 Asterisk 进程

# systemctl start asterisk

获取新的 Asterisk PID

# ps -ef | grep asterisk
root      4925*     1 16 05:07 ?        00:00:00 /usr/sbin/asterisk

检查他们现在在 4096 的文件限制的进程

# cat /proc/4925/limits

最简单的解决方案是重写您用于启动 Asterisk 或/usr/sbin/safe_asterisk.sh 脚本的 systemd 或 init.d 脚本。
