Locked WF/WCF service fails after being called a couple of times in a row

    Greeting all,

    I created a long-running WF/WCF service, and I configured AppFabric to persist it. Usually one instance will run from 5 to 30 minutes.  Now I'm getting this issue: seems it can take about 4 calls at a time -- once it reaches 4, it doesn't respond to new calls, and the new calls will get timeout error.

     

    I tried to configure this from IIS "Configure WCF and WF Server" at Throttling tab, and have changed the Maximum concurrent calls/instances/sessions to 64/464/400, but still get the same issue.

    Any suggestions would be greatly appreciated!
