Is this repeatable?  The sorts of issues which cause a system to *always*
fail are different from the issues which cause a system to *sometimes*

How large is 'testfile' in this case?  Does it work if you try to create
an archive containing a single *empty* file?

The combination of --list-archives working but -c not working usually
points to an MTU problem, but that seems strange given that you say that
no changes have been made recently.  What sort of internet connectivity
do you have?
