Android smack 4.1 flooded with offline messages ejabberd

Question

I am working on chat app by using smack 4.1 and ejabberd-15.11 my scenario is - if client A,B,C,D send messages to E and E is offline then all messages stores in offline storage but when user E comes online android client becomes unresponsive if number of offline stored messages are in huge amount (3000-5000). Please suggest me some solution

Answer 1

ejabberd示例配置文件中的默认设置是将脱机消息数限制为100.

  max_user_offline_messages: 
    admin: 5000
    all: 100

新邮件将被拒绝，发件人将收到错误通知。

如果您的用户是管理员，但您希望从Android以管理员身份进行连接，则还可以配置ejabberd以将管理员的离线消息数量限制为100条消息。
