It is enabled by default, with a low-water mark of 1M and a high-water
mark of 2M.

I would have thought the first sentence made that clear:

        If you are building CVS with the server enabled, you can disable
        server flow control...

None, since it's enabled by default.  Note that flow control only kicks
in *between* files; a file is still sent all at once, no matter how big
it is.

As far as I remember, the concensus was that you had run out of
(virtual) memory on the server machine.  CVS does its best to detect
that condition and report it, but there are circumstances were it is
simply impossible to do so.
