ppp & lqr problem - Warning: lqr_RecvEcho: Got packet size 6, expecting 12 !

[Alen Sarkinovic]

I'm using freeBSD 5.5-PRERELEASE #1 with pppd version 2.3 patch level 5 for
pppoe termination on cable network system for a long time but today one of
our customers reported problem regarding reconection every 2 minutes.
Actualy customer is trying to connect InnoMedia MTA 3328-2R device
(Net2Phone Service) using build in pppoe client software.

I get this error from ppp.log ->

Here is ppp configuration->

(redundant of above???)

Anyone have any suggestions ?
