JABBER(XMPP) Chat rooms sending message causes duplication of message

[thd]

When a user within the chat room sends a message the other users in the chat room can receive it multiple times.  Recipients may not receive the same number of duplicated message.  User A may get it 3 times and user B may get it 5 times.  Below is the version information from one of the users.

thd,
a network log for Core & Jabber is appreciated to debug the situation with these events.
refer to our Wiki about the info how to make network logs

[thd]

Here is the network log.

thd,
yes, your server really sends you five copies of each message, that's true, and looks like a kind of madness.
you need to consult with the server administrator about this strange and unwanted behaviour

[thd]

We have been doing a lot of testing, one thing we have noticed is that when a user does a shutdown/restart Miranda is not changing the user to offline.  We believe this is causing a part of the issue.  I do not see a setting or component to handle that.

[ghazan]

thd,
1. in XMPP server shall forcibly set an offline status, when a client closes its socket.

2. you can force Miranda to move all accounts offline before exiting, using StatusManager plugin
