Hello @dfsn,
Welcome to the forum!
I would add - all of those errors are related to errors, returned by destination, i.e. - nodes which have been targeted as a goal of transfer.
And yes - if your node would fail more than 10% of transfers - it will be disqualified.
To be less scary - each failed attempt will be retried at least 5 times with another nodes (should be 10, but I’m not sure what the current configuration on said satellite).
So be careful when you tune graceful exit parameters above default.
