Seems to be a DB reconnect issue.. user reproducibly reports that at first start/connect it works fine, but after all parties leave and some time passes, like an hour or so, none of them can connect again until it is restarted.

Tested on 2-3 TS servers.

@robi is it possible that the mysql addon ran out of memory or so?

@nebulon does not appear so, all services are green and app mem usage is low.
