Retrying count in Reliable Messaging

I tried with the sample provided in Windows SDK for reliable messaging.This is happening when client is trying to send createsequence message, its trying to createSequence message to service only three times. Afterwards, its throwing exception. Exact exception is shown below,

System.ServiceModel.ServerTooBusyException was unhandled
Message="The Http service located at http://<machinename>/Service/service.svc is too busy. "
Source="mscorlib"

We tried OpenTimeout property on the binding section in FebCTP, but still we are facing the same issue.

Steps to replicate the issue,

1. Stop the IIS service where WCF Service is hosted.
2. Run the WCF client, after two CreateSequence tries (we checked it using Fiddler), it will throw endpoint not found exception or server is too busy exception.

We have tried this using both customBinding and wsHttpBinding. Please let me know if you need more details on this.

Thanks
