Silverlight OpenRIA - duplicated requests

Question

I am using Silverlight 5, .NET 4.5.1 and OpenRIA.

A silverlight client calls a long-run OpenRIA operation. The operation is asynchronous. From the client side I can see that the function from a code is being called just once. From the IIS server-side on the other hand, the WCF function is called multiple times.

What I have logged through Fiddler - the operation was finished with an error. It was invoked once, but with a message „NOTE: This request was retried after a Receive operation failed.”

Request:

    GET http://localhost:11213/ClientBin/KEEP-Web-Services-PayrollListService.svc/binary/GetPayrollList?payrollListId=efb1df5d-993a-4c4b-9fe6-013561547632 HTTP/1.1

The situation occurs in IISExpres and IIS 7.5, locally and remotely.

UPDATE 1.

I have found the reason that causes an operation repeated.

Failed to allocate a managed memory buffer of 134217728 bytes. The amount of available memory may be low.

What I can do to handle it with OpenRIA (former wcf-ria-services)? I see no custom binding to have any effect to OpenRIA.

The problem was IIS in 32-bit. Using 64-bit version solves the problem.

P.S. Visual Studio has an option to use IIS-Express in 64-bit. You can also add to the registry:

reg add HKEY_CURRENT_USER\Software\Microsoft\VisualStudio\12.0\WebProjects /v Use64BitIISExpress /t REG_DWORD /d 1

12.0 - Visual Studio 2013
