Yes, this means the client disconnected rather than replying to a
valid break packet. We don't know why.

As does this.

As do all of the above. The common factor here is "Connection reset by peer".
"Peer" here means your clients - they are dropping the connections. With
a network sniffer trace you would see this.

I'm thinking of just changing the messages in Samba to say something like :

"Client XXXX disconnected without warning: Please investigate your network or
client software to determine why it did this".

It looks like you have some network problems.
