writefd_unbuffered failed to write

[Matthias Meyer]

Hi,

I've installed cygwin and rsync on a vista client and want backup it to a 
Linux server:
On client side (vista) I use rsync 3.0.4 (protocol version 30)
Capabilities:
    64-bit files, 64-bit inums, 32-bit timestamps, 64-bit long ints,
    socketpairs, hardlinks, symlinks, no IPv6, batchfiles, inplace,
    append, ACLs, no xattrs, iconv, symtimes

On server side (linux) I have rsync 3.0.3 (protocol version 30)
Capabilities:
    64-bit files, 64-bit inums, 32-bit timestamps, 64-bit long ints,
    socketpairs, hardlinks, symlinks, IPv6, batchfiles, inplace,
    append, ACLs, xattrs, iconv, symtimes

The backup aborts after different times. In the client logfile I found the 
message:

In the server logfile I see:
full backup started for directory D (baseline backup #8)
Connected to Loredana.mybackup:10025, remote version 30
Negotiated protocol version 28
Connected to module D

:
Read EOF:

finish: removing in-process file Loretta/Pictures...
Child is aborting
Done: 194 files, 92193685 bytes

Now I have 2 main questions:
1. What the reason that client and server negotiate protocol version 28 
instead 30?
2. What is meaning by "rsync: writefd_unbuffered failed to write 4 bytes 
[sender]: Connection reset by peer (104)"

Thanks in advance
Matthias
