Yes it is a .NET client issue! I did not notice there was the .NET client section as well sorry, my mistake!

Yes I am using an evaluation of the Duomo Vivace and recently Colosseo Vivace (to test web sockets as well). But this should not be a problem because I can have unlimited connections while testing for 2 months no?

What I meant with Client Connections is ".NET client sessions". You are right, I noticed that not many .NET sessions can be run at once because of the Thread problem.

I will contact you on support. Thanks a lot
