I agree there should be a limit on the client side, but I did not know how
to do it. The CMsgReader is a somehow low-level object, and I dont see an
obvious way of getting a viewer's configuration item from here.
Could you give me a clue?

Well, this default was the max buffer size vncconfig could manage. The
limit has increased, and the default followed.
I revert this one. It's still true that 256k was enough for every one...
Thanks for your answers.
