Ok, I assume the proper place for this is /var/lib/tftpboot/ltsp/i386/lts.conf

I added the line you indicated. Now that file reads:

Ok, there wasn't already an /etc/ltsp/nbdswapd.conf so I created one
and added the line you mentioned.

my /etc/ltsp directory now has the following files in it.

dhcpd.conf  nbdswapd.conf  syslogd

BTW, Where is the disk space being used? I assume this is on the
server? Could you explain this a little more fully?

The clients are currently completely frozen. I can't get an alternate
tty, however I am game to try this out if I get one that

  If so, here might be an interesting test:
