Just got this error.
The only thing I saw on the web on this was: “This is an internal protocol error. Contact Oracle Support Services.”
As I see it, it means Oracle doesn’t know what I did wrong.
At the end we found out that the error was caused by entering a value of 1.7976931348623157E308 to a NUMBER(38, 8) field. The person that sent me this value meant to send NaN but at the end sent Double.MaxValue.
I am sure this is just one symptom of the problem but maybe it will help someone out there…
