What does this RPC error really mean

NTDEV

I’ve seen the MS HCT storage test “ACPI S3 Stress” report an error with
status value RPC_NT_INVALID_STRING_UUID. What events would cause such a
thing? Has a GUID been nuked (memory corruption), ExUuidCreate not been
able to allocate a GUID (I expect STATUS_RETRY in this case) , or some
other nasty thing?

Searches of Microsoft.com, the OSR NTDEV query page, the DDK source
examples, and even GOOGLE don’t lead to anything worthwhile.

Thanks, MKE.
