I have an working consumer application with offstream posting based on :
I would like to run multiple instances. Each instance posts (contributes) a different set of data.
Sometimes when I start up the 2nd instance, it closes the connection on the first instance and sometimes, it doesn't.
I am using the same machine account/password and the same EmaConfig.xml for both instances.
I'm not sure what I need to change, to make this work properly.
I don't think multiple instances are allowed to connect, using the same set of credentials. Your second instance might be getting past this by being routed to a different server by the load balancer - but it is not always guaranteed to work.
I will check with product team about the correct protocol for multiple applications.
