I have had that error a lot as well when I wanted to make the whole
backup in one go. surprisingly, these errors went away as soon as I
started to upload the subdirectories, one by one.
I did not have time to investigate is further, but there seem to be
problems when trying to upload a lot of files in one process.

Since I know that there had been enough servers online and ready to
server my request, i guess there is an error in the client. My (quite
wild) guess is, that the client does not select a new set of servers for
each file uploaded but tries to always use the same ones. And if one of
these servers does not respond anymore, you get the happyness error.

As a work around you could set the total-servers higher, so it would
still be happy when there are some more not accepting the data...

Maybe take this to tahoe-dev...
