What version of OpenSSL are you using? It seems there may be a bug with 
0.9.8d:

   http://www.mail-archive.com/openssl-dev@openssl.org/msg22413.html


In which case, you might like to downgrade to 0.9.8 to see if it fixes 
the problem.

As far as I can tell, this error is not actually causing any data loss. It 
simply means that the stream was not shut down correctly, when it was 
already in the process of being shut down.

However, bbackupd will discard its internal state when this happens, so it 
will operate less efficiently, generate more network traffic and take 
longer to back up.

Please let us know if downgrading fixes the problem.

Cheers, Chris.
