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 GB
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 ?

The storage server reported an exception that appears to be a bug in code related to the upload helper. I haven't seen this particular error before. Is a helper enabled?

Xavier wrote:

yes there was an helper working

this is necessary in our design
as the nodes are connected by low speed adsl and the helper is on a high speed internet connection.

actually it was not possible to backup more that 2-5 gByte of data at same time. directly on the global network
we always go to a kind of error or infinite loop.
