Description truongkhanhit 2012-12-22 08:30:42 CET
My name is Khanh. I'm trying to verify the FDDI protocol by using Uppaal. I download the benchmark at There are many FDDI models with different number of processes. When I try with small number of processes, for example less than 30, then Uppaal works well. However when I try with large number of processes, Uppaal has exception right after I press the "verifier" button. It is the IO exception: "Server connection lost. Establish direction connection to local server". Then there is a notification from Windows which tells that the server.exe has some problem.

I tried both Uppaal 4.0 and 4.1 and this happens the same. Can you check for me?
