XPA.list() or XPA.find() do not find my XPA server

In principle, XPA servers are able to automatically launch an XPA name-server for their type of connection (internet or Unix socket) if none is running. If an XPA name-server is killed or stop working, XPA servers registered by this name-server have to reconnect to another name-server. In SAOImage/DS9 server, this can be done by using the menu File > XPA > Disconnect and then File > XPA > Connect. If you have several SAOImage/DS9 servers, you may have to do this with each server.
