I have installed ppp-sunos4.1.pl6.tar with patches:
   ppp-sunos4.1.patch6
   ppp-sunos4.1.pl6.mem_leak.patch

on a Sparc1.  I am running the NeXT PD version of PPP from home.  I
had a similar setup working from a Sparc IPX and my NeXT with no
problems.  However, now, when I try to FTP a large file on the new
setup, I get a system crash and a reboot.  The transfer starts
normally and after about 60K, the /usr/adm/messages file gets (and the
machine reboots):

Anybody have any ideas what the problem may be??  Help would be
appreciated! 

Steve
