Maybe try to enable debug mode on the cvs core programme (cvsnt). Not
sure if dumping network traffic might help. You can also watch the cvs
command running by logging on to modula3.elegosoft.com via ssh.

You should really first check quality of your network connection to
modula3.elegosoft.com and possibly try if update works with other
implentations of cvs.

Cheers,

Ronny
