EDM service for PDS giving odd errors, help?

[AK]

Okay... so we use the EDM to perform the <ResourcesUpdate> request and are
receiving some funny errors inconsistently.

#Series 1 in Event Log (does not always occur)
-Soap error: An unanticipated error occurred during the processing of this
request..
-Soap error: Executing method SubmitWithCookie failed.
-Soap error: Execution failed with an HRESULT of 0x8000ffff.
-Soap error: Executing method SubmitWithCookie caused an exception.

The http post size is set very high in both IIS an MSSOAP and the timeout in
IIS is very high. Anyone experience anything similar?

#Series 2 in ProjectServer.Log (always occurs)
-out of a XML file with 250 requests
-about 199 succeed
-7 fail for not having a valid NT login id
-44 fail with no visible error in the logs... phantom failing.

How can I figure out what the deal is? The syntax is as follows:
<Request>
<ResourcesUpdate><RESOURCES><RESOURCE></RESOURCE></RESOURCES></ResourceUpdate>
<ResourcesUpdate><RESOURCES><RESOURCE></RESOURCE></RESOURCES></ResourceUpdate>
....
</Request>

also, the following error occurs 20 mins later and may or may not be
related...

-Faulting application w3wp.exe, version 6.0.3790.1830, faulting module
ntdll.dll, version 5.2.3790.1830, fault address 0x0001e5f7.

I did a lot of analysis using IISDebug Tools. If anyone is interested, this
seems to be an inherint problem with the EDM for RBS updates. When
attempting to update the RBS code, I strongly recommend using the PDS
directly. The syntax is nearly identical and no errors.
