Initiating key re-exchange (too much data received)

I'm trying to transfer a rather large file through sftp. I'm getting these lines in the log:
> 2018-03-05 11:10:21.493 Type: SSH_FXP_OPEN, Size: 71, Number: 4172291

My question is, when it initiates a key re-exchange, does that mean it is starting the transfer over? Or will it eventually finish?

Re: Initiating key re-exchange (too much data received)

The key re-exchange is transparent to the transfer. I.e. it has no impact on it.
