Subject: cannot reconnect after error
Alex,
I encounter the following situation:
- when the server is starting up, and client is in the process of connecting
- On BoshException error, client app closes the connection (see SND: </stream:stream>)
- however, next come server responses
- Matrix library continues with the login
- But, server, I think, does not response to "auth" message (probably seeing </stream:stream>)
- Once, this happens, I can't seem to close the XmppClient. ActiveStream is true, and calling Close() on XmppClient object does not seem to reset ActiveStream.

we have not seen such problems before. Please provide a test case and exact descriptions how to cause this exceptions.

Yes, I'm still trying to reproduce the problem.

In the meantime, I was wondering, when client side tries to close the stream (sending </stream:stream>), should the client ignore any subsequent messages from the server?

The session is closed when you get the OnClose event. Every incoming stanza before OnClose should not be ignored.

Another question, in case of server not sending </stream:stream> when we close the stream, what will the Matrix library do? What client app should do to re-initialize the connection?

when you call Close() on the XmppClient then MatriX is closing the stream, and the server MUST also close the stream. So this case will not happen when there is not a bug in the server or the client.
