I don't know what is going on, but I don't think it is a problem with
netatalk specifically. Digging into the relevant code:
dsi_stream_read calls the standard POSIX read function. It returns -1 on
an error and sets errno. In the log above, we see "dsi_stream_read(-1):
Connection reset by peer", which indicates that the other end of the
tcp/ip connection either timed out or closed the connection with a
standard tcp/ip FIN/ACK packet.
The "dsi_stream_write: Broken pipe" means that it tried to write to a
socket whose reading end is closed, which makes sense from the
dsi_stream_read error above it.
Do you only have this problem with certain client machines, or does it
happen to all of them? Are there any Apple updates for the networking on
these machines?
