There hasn't been any change in the networking code in CVS since
sane-backends 1.0.16. The error messages means that on the server the
backend tries to send a big amount of data to the client. This might
be cause by bugs in the backend, crashing network connections or an
attack from outside.

Turning on debugging may help to identify what's going on:
export SANE_DEBUG_NET=255
