it will go like this forever.
So you must try to find the offending rows on both sides and explain how did it happen.
I repeat, this is serious, and not supposed to happen.
The system expects from you to resolve the problem manually and advance the position as needed to overcome the error.
Until you do this, you'll keep getting this ERROR.
Read the docs.
