Hi guys, I have no idea why, but a customer reports receiving that error code in a Windows Server 2016 VM during a sequence of INSERT statements, and, as there is no stack trace from that unmanaged part, I have no clue whats happening. Does that error code even make any sense, can I look this up in the sources, for potential reasons? Also, are there debug builds available for the Interop or do we need to rebuild them ourselves? Thanks BR Florian
