In reply to How should /etc/hosts be configured?:
Same here with my unit ( http://www.spectra.com/ibm/ibm-systems/16/index.htm ) works like a charm. Thanks!
The problem joining a room is the same that becoming online in a shared group: you have 50.000 contacts (or room occupants), and the server sends an "online" presence packet to each one. Everytime you become "away" or "busy", another 50.000 packets are sent. And this happens for each one of the 50.000 contacts you have.
