Bug description

Please, give us a precise description (what does not work, what is expected, etc.)

Matrix Gateway having some sort of issue.

• It also sends a lot of join events (related to Matrix Gateway: ejabberd sends "join" while already joined #4386?), apparently at least once every second.

• Receiving a direct message from Matrix, the first message shows up as an private message in a MUC, but then everything else shows up in a seperate conversation (correctly then).

• Joining some chats takes forever and never completes. Other chats, even with addresses on the same server, work fine.

• Restarting ejabberd did not seem to do anything useful

It currently is not usable, unfortunately.

Oh another thing I noticed:

The join events do not show up in direct conversations, like when people send me a direct message.
