error while doing tahoe backup

[freelab xavier]

we are continuing of test of tahoe platform


mainly using the tahoe backup function


while making a backup of quite a quantity of data 30-40 go

here are the errors i have


(as the backup is not completed no files are accessible, which i sad by
design)


the error messages are not that clear


what shall I understand from those errors ?
