We first encountered this problem when we were importing a CSV file of approx 8600 records.
We did the integration on the same workstation we have for years and until recently not encountered errors.
Error Message
The Following problem was encountered during destination uninitialization
The RPC server is unavailable. (Exception from HRESULT 0x800706BA)
Similar issue - larger value in the number of records in the import - same error message

Our Solution
We first cut the number of lines on the CSV in half and that did not solve the problem.
We then cut the number in half again and we were able to run the import.
The difference it appears was the number of Integrations with Warnings
was dropped below 1,000.
In the first pass (all 8563 records) when it failed there were 1,729 Warnings
We have the number of errors and warnings set to 10,000 on each but yes the system still fails.
Wondering if there has been a resolution to this for the general release of the software.
We are running GP2013 and IM 12
