FTP transfer hangs in Solaris 8

I tried FTP'ing a 1GB file from a Windows 2000 laptop to a Solaris 8 machine
and the process kept hanging. I had no problem transferring a 500MB file
from the same laptop to the same Solaris 8 server. Here's what I saw:

>From Windows 2000 server, I FTP'ed to the Solaris 8 server, connected as
root (with appropriate password), set type to binary, turned on hash marks,
then tried to put the 1GB file onto the Solaris box. My Windows laptop
immediately hangs.

I tried eliminating the switch from the equation by using a cross-connect
cable directly from the laptop to the Solaris 8 server, but that didn't
help. I had no problem transferring the file to a Solaris 7 machine, and it
even transferred across the network to a different Solaris 8 machine.

I tried installing an FTP server on my Windows 2000 box and then using the
Solaris 8 server as the client. In my log files, I see the Solaris 8 client
log in and request to get the file, but nothing after that (and, of course,
the Windows 2000 client hangs).

Does anyone know of any setting in Solaris 8 that might tell a server to
ignore FTP file transfer requests greater than 500MB? Anyone have any
suggestions as to what configuration settings I should look at on the
Solaris 8 server?
