It was worth a try but I see exactly the same behavior on the media lab jabber server. One thing I think I am noticing. It seems like one machine at a time is connected to the Jabber Server. What happens when a machine connects? Is there anyway that one machine connecting could cause another to disconnect? Are these machines in some way replicating something about them when the server things it should be unique? Could there be some sort of firewall or a caching service that decides its a duplicate and cuts one of them off? <div class="gmail_quote">On Wed, Jul 8, 2009 at 11:17 PM, Benjamin M.

Have you tried other servers? For example, <a href="http://schoolserver.media.mit.edu" target="_blank">schoolserver.media.mit.edu</a> has been very reliable for me. OLPC ran collaboration jabber servers for very large numbers of people following G1G1, and the only major problem was server overload (when serving far more than 18 users). It is possible, and maybe the people who built those servers have some advice. --Ben </blockquote></div> -- Caroline Meeks Solution Grove Caroline@SolutionGrove.com 617-500-3488 - Office 505-213-3268 - Fax
