If you detect the situation, I'd suggest that you just seek to correct
position in your local file and then upload the rest of it with
CURLOPT_APPEND and an INFILESIZE that is the rest of your local file.

If you could show us a trace of what happens when you do this, it would help
us a lot more to understand what the problem is and how to correct it.

Use CURLOPT_DEBUGFUNCTION for that.
