I suspect that this is not a limitation imposed by ftp but rather a
parameter in the kernel called the ulimit.  The ulimit limits the size
of a file of a process and its children.  This is often set at one
megabyte.  This supposed to prevent runaway processes from eating up
available filesystem space.  My feeling is that it causes more problems
than it prevents.

If you are root, type "ulimit 8192" and you will be able to create
files of up to 8192 blocks in your current shell.  This does not set
anything for other users or for root at a later time.  To change the
system-wide ulimit value, you have to reconfigure your kernel.

The above information is for System V.  It has nothing to do with
Berkeley UNIX.
