Function sequence error

From time to time in our logfile there is an exception
"Error -1: [Microsoft][ODBC Driver Manager] Function sequence error"

Turns out that this exception does occur when we call the ApplyUpdates function from the ObjectManager.

Using Microsoft SQL Server, using TMSSQLConnection in order to connect to the database.

Are there ways to find out what causes this Function sequence error ?

I'm afraid you will have to provide a way for us to consistently reproduce the issue. It looks like an issue that occurs only in very specific situations.

Unfortunately we are not able to create a sample application in order to reproduce the steps.
Meanwhile we have changed and replaced TMSSQLConnection with TFireDacConnectionAdapter and now we see no issues anymore.
