Quick correction, 'Lost connection to mapserver' has nothing to do with XMPP. It means that the client can't connect to the Paragon Chat process on your computer. It's purely a local issue -- either Paragon Chat crashed, or something is fighting for resources with it and it can't respond fast enough.An XMPP disconnect will manifest with everybody else suddenly disappearing and losing access to global channels, along with a system message in the chat window.
