[Sugar-devel] [support-gang] Collaboration woes

[Thomas C Gilliard]

Jim;

I want to my 2 cents to this. Here is a brief history as I remember it:

I have done a lot of testing of collaboration using the (default) 
jabber.sugarlabs.org connection.

It is provided by caroline's solutiongrove.com and maintained by Dave 
Bauer (daveb) .

Several months ago the jabber had gadget installed ( I think by tomeu? 
)In an effort to make  the jabber handle  the large numbers of 
connections that were swamping the server in 1 to 2 days times , 
effectively  freezing it up cold.

The result is that now it keeps running fine but only serves up 20 
(random?)buddies when you make a connection. (You will not get a new  
set of  20  buddies if you restart Sugar... ) Also: there are many 
"ghost" connections littering the jabberserver.  ( on a 0.86 version of 
sugar you will notice that these "ghosts" have the user color.) They 
occupy spots that should  be showing new connections. When daveb 
restarts the jabber this is momentarily cleared up until the loading of 
new users gets too large.

The overall result seems to be a non-functional collaboration 
neighborhood. It is a sham.

This does not appear to be a problem for school-server setups using 
their own jabber (I assume without gadget loaded) as I have not heard of 
any complaints about it on the list.

Hint: If you are on the same network, you can collaborate if you delete 
the entry for jabber.sugarlabs.org in the control panel on your sugar 
entities.
