Well, the server shouldn't drop random data like you say, but it could do
incomplete writes to a client.  That could cause data to be mangled.
Anyway, if that's your problem, we could just close the socket from the
server to the client in case of a write failure, and make the client clean
up his buffer, if this isn't done already.

BTW: could you try to run the server with a higher log level and send the
output when the bug arrises freeciv-dev?
