The experimental Horta version (see the explanation in #416) was reconnecting to the server exactly every 2 hours. It has line `xmpp.timeout_ms=900000` in its config. That's not a big problem, but it should be fixed. Current hypothesis is that it's the problem with XMPP pings (I had a similar issue in [Kaiwa](https://github.com/ForNeVeR/Kaiwa)), and I think there was a way to tune them in Smack. Probably we'll need to add a facility to log all XMPP messages to debug this. Note that these reconnects seems to be completely encapsulated by Smack: the underlying application cannot see them.
