Hi,
In our case there were a few connected to simple mesh but we rebooted them
and made sure all were connected to the server mesh. It does look like the
issue on ticket 6884. Otherwise, the server works very well with our class
size of 25.

There are two possible reasons.
The first is that you are still using the mesh, and mesh routing with
that
number of laptops is capricious at best.
The second is a known problem exists which can also cause this:

We need to get ProcessOne to fix this problem with ejabberd.

Trying out the school server for the first time at a training
session in a Solomon Islands deployment. With 23 trainee teachers,
using G1G1 XO-1 laptops with build 703 (update 1). All registered
successfully and all able to connect to and access the server.
It seemed to be working 100% but then we started noticing that it
was not unusual to be missing some XOs on the neighbourhood view.
This was apparent with an exercise where people in groups of 4-5
tried to locate each other and make friends, in order to manage
sharing in smaller groups. Almost all of the groups could not
locate all of the other members of their group.
I checked, all were registered, connected to the school mesh and
all could see most of the other laptops. But not 100% reliably all
of the others. Rebooting did not help much.
This was in a very rural location with no cell phones, no wireless
access points apart from the XS active antenna, in a small wooden
classroom 6 x 6m. There was, however, an old inverter running; not
sure if that might have been making RF noise. We were running the
school server from a battery.
I was using an XS set up to demonstrate the concept only, on a 4-
year old Toshiba A3 laptop. I have a prototype active antenna.
So (a) should I expect all the other laptops to be visible? And (b)
what is the maximum number of XOs per server?
Server access seems very robust and very impressive. But the
unreliable collaboration is a disappointment, it was not much
better than a similar size group using the simple mesh. What could
be the reason?
