Hi,
Sorry for not having answered before, I couldn't reach my mail.
The reality is that I don't have any explanation to give ! I don't see anything
in Jonathan that could depend whether the computer is really connected or not.
The tests I perform have never shown any problem with threads. But it doesn't
mean the bug is not in Jonathan.
Could you please give me some information about your configuration: number of
machines involved, where are the servers, where are the clients, how do they
interact, when are server objects created ? This would help me tracking the
problem on Jonathan's side.
Regards,
Bruno
