Sounds to me like you have a hardware problem with either the client
that is commiting these files or more likely your CVS server. The CVS
server I maintain had a memory problem recently which on rare occasions
caused 1 bit errors in the ,v files. Try swapping out various hardware
components until the fault goes away.

TCP is already quite good at this. However all the network error
detection in the world won't help if it is the CVS server that is
mangling the files.
