mysql - Ejabberd Disco Itteam 不会来

Question

版本:17.11

平台:ubuntu 16.04

使用 mod_muc 配置，有时迪斯科项目根本无法加载。 这是我用于迪斯科项目的配置。这是我在崩溃时发现的崩溃日志

mod_muc:
  db_type: sql
  default_room_options:
    - allow_subscription: true
    - mam: true
  access_admin:
    - allow: admin
  access_create: muc_create
  access_persistent: muc_create
  history_size: 100
  max_rooms_discoitems: 1000
  max_user_conferences: 50
  max_users_presence: 50

此外，在加入先前可用的同一 muc 时，无法获得连接。如果我重新启动服务器，一切都会正常，并且在某些时间后 muc 不会出现

Answer 1

什么 ejabberd 版本？你是如何安装它的？

你的default_room_options的语法是错误的，你真的是这样使用那个配置的吗？

您对库存安装进行了哪些更改？我的意思是:您是否设置了一个由多个节点组成的集群，您是否启用了可能干扰 mod_muc 的其他模块...？

最重要的是:您已将 max_rooms_discoitems 设置为 10000。该服务有多少个房间？该选项应设置为一个较小的值，因为请求 10.000 个房间的 discoitem 意味着向每个房间请求信息，这意味着 10.000 个查询，这可能会产生未知的后果。如果您设置较低的值(例如 100)，您的问题是否会重现？
