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 星号 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

星号 PID：1130

检查进程的限制。最大打开文件软限制为 1024

root@trueringless-asterisk:/home/esundberg# cat /proc/1130/limits

编辑 /etc/asterisk/asterisk.conf

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

停止星号进程

# systemctl stop asterisk

确保星号已停止

# ps -ef | grep asterisk

启动星号进程

# systemctl start asterisk

获取新的星号 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星号或 /usr/sbin/safe_asterisk.sh 脚本的 systemd 或 init.d 脚本。
