I have a rather simple worflow hosted on AppFabric. I call it through a WCF endpoint using netTcpBinding, and it calls 2 WCF methods, also via netTcpBinding, hosted on the same server also on AppFabric. I can load test both of the WCF methods being called
by the workflow simultaneously without any problems. However, when I start Load Testing the workflow, after a few seconds, when I'm around 10 simultaneous users, the WorkFlows locks up completely, and I'm unable to find out why. All clients starts raising
Open Connection timeouts.
The problem is not locking on the SQL Server database, because I monitor it, and it's all go. All tables involved are lock free. I think the problem might be on MSTSC, since I start a transaction scope on the workflow, but how could I detect the problem
there? The dashboard on dcomcnfg really doesn't help at all.
How can I find out where's the problem? What could be the problem. Any help would be greatly appreciated.
