File "disappeared" and "end of file" error messages?

[Bruce Pennypacker]

Hi all,

We have a couple CVS repositories that we've been using without incident for
quite some time now.  Some folks are now reporting the following errors when
working with fairly large binary files:

$ cvs co 3rdPartyR/c++/i18n/i18n.tar.gz
U 3rdPartyR/c++/i18n/i18n.tar.gz
cvs [checkout aborted]: end of file from server (consult above messages if
any)

Despite the end of file message the file was successfully checked out - it
can be gunzipped & untarred successfully...

The second error that another person is seeing is:

cvs server: warning: new-born 3rdPartyR/c++/i18n/i18n.tar.gz has disappeared

What do these errors mean?  Why are we getting them if the files seem to be
accessable?  Any help would be greatly appreciated!

Thanks,

-Bruce
