如何增加在 Ubuntu 上運行的 Asterisk 的打開文件描述符

Question

我遇到了這個，我發現只有一篇關於這個的帖子有修復，但不是那么清楚，而且已經有幾年了。

Ubuntu 20.04 星號 16.9

錯誤信息：

[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

星號 PID：1130

檢查進程的限制。 最大打開文件軟限制為 1024

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

編輯 /etc/asterisk/asterisk.conf

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

停止星號進程

# systemctl stop asterisk

確保星號已停止

# ps -ef | grep asterisk

啟動星號進程

# systemctl start asterisk

獲取新的星號 PID

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

檢查他們現在在 4096 的文件限制的進程

# cat /proc/4925/limits

最簡單的解決方案是重寫您用於啟動星號或 /usr/sbin/safe_asterisk.sh 腳本的 systemd 或 init.d 腳本。
