【问题描述】：
我在我的服务器上安装了 bigbluebutton，它工作正常，但突然麦克风无法连接，一段时间后卡在“回声测试”中，我会收到 1006 错误，我已经测试过：
FreeSWITCH fails to bind to IPV4Anchor link for: freeswitch fails to bind to ipv4
In rare occasions after shutdown/restart, the FreeSWITCH database can get corrupted. This will cause FreeSWITCH to have problems binding to IPV4 address (you may see error 1006 when users try to connect).
To check, look in /opt/freeswitch/var/log/freeswitch/freeswitch.log for errors related to loading the database.

2018-10-25 11:05:11.444772 [CRIT] sofia.c:3049 Cannot Open SQL Database [external]!
If you see these errors, clear the FreeSWITCH database (BigBlueButton doesn’t use the database and FreeSWITCH will recreate it on startup).
$ sudo systemctl stop freeswitch
$ rm -rf /opt/freeswitch/var/lib/freeswitch/db/*
$ sudo systemctl start freeswitch
但这并不能解决问题。
这是bbb-conf --check的输出：

我测试了我发现的所有内容，但问题仍然存在。有什么办法吗？ 提前致谢。
