That would be consistent with the state of the net earlier in the week. It
would seem that this error is simply a symptom of impatient users dropping the
connection. Of course, it may be a symptom of frustrated users waiting for a
long time and then dropping the connection. Presumably what happens is that
during the initial handshake some packets go missing and when they finally
get through the client has already closed the socket.

It would be really nice to see a packet trace of one of these events to confirm
this theory ... anyone kitted up to do that?

Cheers,

Ben.
