I'm getting an error "The entry '*' has already been added. (C:\Program Files\Microsoft Service Oriented Infrastructure\Microsoft.MSE.Runtime.ServiceHost.exe.Config line 76)" when testing a simple service (CalculatorWCF) using a new MSE Universal Service Tester v7.0.0.0.
When I commented the line #76 in the Microsoft.MSE.Runtime.ServiceHost.exe.config like it is shown below, everything works fine.

   <!--<add address="*" maxconnection="10"/>-->

I believe I remember I had experienced the similiar problem with early version of MSE 6.x., which I "fixed" the same way - by commenting the line in the config file.

Is there something I need to do otherwise? What is implication of removing this line from the config file?

The maxconnection element sets the maxmum number of outbound simultaneous connections to the "address" in this case any server.

there might be a conflict if this settings is also present in the machine.config.  could you verify if that is the case?

Tony, you're correct.
I did find the maxconnection setting in my machine.config, which is currently set to 25. This should not affect the MSE performance, right?

well...  it depends on your specific requirements.  recommended values  range from 2-12 * # of CPUs in your machine, but I think you have to determine as you also don't want to create tons of simultaneaous request as that introduced contention for CPU resources.
