I don't think you get a message. I think the browser times
out. The limit to Training concurrent users is the number of users
interacting with the Breeze SQL server at a given time. Typically,
this will be short as it is just reading or posting data and then
returning it to the browser. Once the request is done, the
connection is released. This is the best recollection I have of
what the MM rep told me when I asked this question.
