I've been fighting this one too, and fixed it!

Add the following lines to your ppp.conf (on both ends if necessary)
 disable lqr
 deny lqr

iijppp will hangup the line if more than 5 echo packets are lost during 
the session.  This is of course really easy to do if you've got an FTP 
going on.  
Disabling LQR prevents iijppp from tossing echo packets around and thus 
fixes that problem.  The code could could definately use some work 
to implement a more intelligent LQR system that would perhaps reset the 
counter once it received a valid echo reply.
